This App seems to infiltrate the MacOS and install pieces of it all over MacOS and God know what it is doing. I choose to delete it after installing the free version as I already have similar products, and I felt it was impacting performance and/or causing some stability issues. It literally took me hours to search out all the pieces and delete them . As such I cannot recommend this product.

Dear MacUpdate Users, I have stated this before on MacUpdate but, since some people didn't get the memo, I'll say it again: Quickie, one-liner 5-star reviews on this site are WORTHLESS. I would also say that quickie, one-liner 5-star reviews by people who purport to be Mac malware experts (I'm referring to "Hanspoot" just below) with "over 300" clients are EXCEPTIONALLY worthless. Especially when that 'expert' is claiming (it actually sounds like boasting) that his 300+ clients are averaging 5 infections PER MONTH. My friends, if you are averaging 5 infections per month, while you pay both a Mac consultant, and also for anti-malware software, your Mac consultant is not only incompetent but irresponsible. A properly protected Mac, with a properly trained user (and a reputable Mac consultant should be a *teacher* for his or her clients, rather than leaving them uneducated and vulnerable in order to suck money out of them) should not get 5 infections in A YEAR. You especially want to avoid a consultant who allows you to get 5 infections per month while using a "real-time" scanner like the paid subscription version of Malwarebytes. This is beyond irresponsible -- it is appalling. For that kind of money, you should not be getting ANY infections. That's the point of "real-time" scanning, and why you pay a premium (in money and performance) for it. Also, please, be skeptical of reviewers who make silly, boastful claims that can't be substantiated. This is something akin to what Malwarebytes does with it says that it "crushes the latest threats" and other hyped-up nonsense. * * * Now, if you want to see a useful review, scroll down to "Jimw's" comments on May 17, 2019, where he points out that not only does Malwarebytes cause instabilities (inexcusable in and of itself), but its so-called "uninstaller" doesn't actually uninstall everything like it should. It leaves bits and pieces of Malwarebytes junk all over the place. This is beyond inexcusable -- it's disgraceful. -SB P.S. And by the way, "Hanspoot," I don't get money from any AV vendors as you insinuate in one of your snarky comments below. I don't actually recommend ClamXAV though I do subscribe. The Intego VirusBarrier Scanner works just as well as an on-demand scanner -- and it's free. And I actually do use and recommend the older "Malwarebytes Anti-Malware" program (v.1.3.1.628) It still works very well, much as it did when Thomas Reed originally developed it -- a tight, light, free scanner for active infections -- before Malwarebytes (the company) turned it into a bloated piece of expensive corporate crapware.

I had tried using it many months ago. During the time I was using it I started to have machine instabilities which I finally traced to it. So I chose to remove it, and even tried its so called uninstaller. Afterwords I still was occasionally present with some evidence that pieces of it were still lurking on my machine. So I used a few in depth tools to check for invisible and system file and found pieces of it still all over my computer. After several hours of work I finally got rid of all of it; at least I believe I did. Since then the problems that I attributed to it have disappeared. Given its bad behavior on my machine and the way it inserts itself all over MacOS, I have come to believe that the text 'bytes' at the end of its name should be removed as its name without 'bytes' seems much more appropriate.

This *was* the #1 paid utility in the Mac App store until Apple yanked it today. Malwarebytes has been exposed as harvesting browser history (Chrome, Firefox and Safari) and sending it to a server in China. The company has apparently been changing its name and the name of the software to circumvent detection.

You've got it wrong: The app you're talking about is "Adware Doctor" (see https://9to5mac.com/2018/09/07/adware-doctor/).

Since then, apps by Trend Micro have been found to do the same (see https://9to5mac.com/2018/09/09/additional-mac-app-store-apps-caught-stealing-and-uploading-browser-history/).

I have yet to hear this reported for Malwarebytes.

Surprised by all the negative reviews! Been using Malwarebytes since it was Adware Medic, and have had zero issues with it. Malwarebytes does install some daemons that hook into the system in order to run in the background as well as being able to remove certain pieces of malware that have their hooks in the system as well. I've run this on other people's systems that have been acting up (or have obvious signs of malware like Genieo and MacKeeper), and Malwarebytes had done a great job in detecting and removing the threats. The installation process is pretty seamless, but you are asked during the process to approve the installation of a system extension via going to System Preferences -> Security -> General. But this is a total normal thing when an application needs to install a system extension (such as Little Snitch). In addition, if you are unhappy with Malwarebytes, removing it is also quite easy. Going into the application, click on the "Help" menu and choose "Uninstall Malwarebytes." It's as simple as that. And finally, if you are having issues, the Malwarebytes developers are very responsive. Instead of posting negative reviews here, I suggest actually contacting them to see if they can help.

Once installed this product is next to impossible to uninstall or quit. Even if you force quit it in Activity Monitor it restarts itself. During installation it inserts files in places normally hidden from users. In order to remove it I had to set up a special search routine with Finder including System Files and Invisibles or use File Buddy to get to all its elements for complete removal. It actually seems to behave like malware. For these reasons I can not advise even trying it in its trial or free mode. It is also subscription based for the full version. Does it do its job? Not sure since, given the amount of resources it uses, I took it off before I was ever attacked by malware. I know this because of similar products I use. I can't say for sure if it was the root cause but while it was on my system I upgraded my MacOS to 10.13.5. After that my machine refused to go to sleep. In order to fix it I had to do a complete backup of everything; reformat my primary drive; and do a complete reinstall and restore to fix the issue. Currently I cannot conceive of a time that this product will ever be installed on any of my Macs again.

Actually I used FileBuddy to find all the associated files and deleted all of them. I suspect the uninstaller is not that complete and may leave some stuff behind. The other option would be to create an advanced custom find for anything containing the word 'malware' and include system and invisible files in the search. However this is somewhat more challenging to do than using FileBuddy but is an option if you do not have or want to purchase FileBuddy which I consider to be an essential App to have in my Mac toolchest.

Impossible to Activate license for Malwarebytes Premiun. If you are running Mac OS X High Sierra, don't buy this. Unfortunately I did and I can't do anything with it. Not even with the latest version 3.3.32. I purchased Malwarebytes Premium on 8aug17. At the time I was using Mac OS X El Capitan. It worked fine on that machine. On May 25, I had to replace my old Mac with a new iMac running Mac OS X High Sierra 10.13.5. I had the latest version of Malwarebytes, 3.3.26, installed but it won't open at all. I've run Onyx on the machine and rebooted but Malwaresbytes still won't open. I sent a message to support about this problem and asking if it runs on High Sierra and got back an invitation to register and set up an account. I did that. Still no response. I decided to give it a few days. On June 17, I downloaded the update (3.3.32) hoping the problem was fixed. But it still won't open. I went to the Malwarebytes page and logged on to my account. That worked, at least. They have very specific instructions for installing on a Mac, which I had already done but did it again following the steps in the instructions after trashing the one that failed. I got to the step where you have to allow the Mac System Preferences to allow some extensions from Malwarebytes. I tried to do that and Mac System Preferences Security/General .told me it blocked Malwarebytes and that I need to click Allow to let them in. I opened the padlock to make the change but still cannot click the Allow button. I moved to the Security/Privacy tab and added Malwarebytes into the Accessibility authorization box to allow it to control my Mac. That didn't help anything after going through all the steps as before. Still can't Allow Malwarebytes to complete the install. So back in the installation, I tried Do It Later for the Mac System Prefs and the installation said it was installed. . I open Malwarebytes and discover I am way back to the Trial Version 3.3 I try not activate the license again but it tells me I have to go through everything above all over again. But still Mac System Prefs won't allow it. I go back to the installer / open Trial version and get a new notice that it is already activated on another machine. Ah, the old Mac. There is a button to Deactivate on all devices. I did that and was told it was now deactivated. Tried all the above all over again--still no go. Tried to go to the Malwarebytes support page and they want me to log on. It won't recognize my account even though I'm logged on in another tab. I try to use Chat--they are only there on the weekends. Tried their email link--Apparently their email system doesn't run on weekends either. I went to the Forum and tried to log on. It said my email address wasn't associated with any Malwarebytes account. What?? So I checked the Use Anonymously box but it wouldn't accept that--it refreshed the login box and filled in my email address and password that had worked but, of course, now it isn't a recognized account. I checked the list of accepted browsers and my Safari browser is on the list of browsers they accept. I am throughly disgusted with the complete waste of time and energy I put into this. I quit. Tomorrow I will uninstall (although from comments below that is also impossible--but I will try. Then contact Billing to stop automatic renewals and request a full refund. Don't buy it if you are running Mac OS X High Sierra.

"Malwarebytes" is a glorified, over-hyped adware scanner, and little else, based on "Adware Medic," a free program written around 2014 by Thomas Reed. Note that the software's name ("Malwarebytes") used on MacUpdate, curiously, is not the one used on the company's website. That name is "Malwarebytes for Mac." Also, it is described here (under the name) accurately as an "Adware removal tool." That description is not on the website, and the company strongly suggests that the software does much more, e.g., "Removes malware, including Trojans." According to the Release History on the Malwarebytes website, "Malwarebytes for Mac" was launched on July 31, 2017, starting, oddly enough, at version 3. This was done evidently for marketing purposes, to align it with products for their other platforms. Malwarebytes was already offering a product called "Malwarebytes Anti-Malware for Mac" (call it MBAM), originally launched on July 15, 2015. MBAM was essentially a renamed version of Mr. Reed's "Adware Medic," issued when he went to work at Malwarebytes. According to the company's website, the last update to MBAM, version 1.3.1, was issued on October 17, 2017. According to the company's website, MBAM was on sale until February 15, 2018. It's "End of Life" is scheduled for August 15, 2018. (Who knew?) The nomenclature used by Malwarebytes is confusing enough on these overlapping products. But more confusing, and more likely deliberately deceiving, is the notion that they remove all "malware," a term the company never bothers to precisely define. What MBAM (and before it, "Adware Medic") does (or did) was to remove "active" infections of a small subset of what most Mac security people refer to as "Mac malware." I have no reason to believe that "Malwarebytes for Mac" expands on that subset. Nor do I believe that Malwarebytes even publishes what is included in that subset, though you do see the names whizzing by as MBAM runs. They certainly do not inform customers that it is only a fraction of all Mac malware. On the contrary, they strongly suggest that "Malwarebytes For Mac" all you need to protect your Mac. You can download a "sample" of 108 instances of actual Mac malware from Patrick Wardle's objective-see.com. Unpack them and you have 108 pieces of live "malware" (by any definition) which are just waiting for you to click on them so they can infect your Mac. I ran ClamXAV against this sample and it found just about all of them. How many did MBAM v 1.3.1 find? None. When "Malwarebytes for Mac" (which, again, is known, incorrectly, on MU as simply "Malwarebytes") first came out I loaded it up and ran it. But after trying to use it, and after reading the reviews here, I unloaded it and went back to MBAM. I do not know if "Malwarebytes For Mac" would find any of those 108 instances of malware, but I seriously doubt that it would. Someone else can test that. However, I did upload a half-dozen or so of the malware samples to virustotal.com. On Virustotal, "Malwarebytes" (presumably the latest version of "Malwarebytes for Mac," though the site didn't specify) found the same number as MBAM did: None. I urge you to read this review of "Malwarebytes for Mac Premium" from August, 2017, a month after it launched: <https://www.pcmag.com/article2/0,2817,2487706,00.asp> This article confirms that "Malwarebytes for Mac" only scans for "active" malware. It refers to an independent testing outfit that does not certify "Malwarebytes": <https://www.av-test.org/en/it-security-product-overview/> I conclude that "Malwarebytes for Mac" is still little more than a scanner for active adware infections, and perhaps a few other bits of malware, already running on your Mac, with a paid option to do real-time checks for a small (and again undefined) subset of Mac malware. It might do a decent job with this, but the point is that, in boasting to Mac users that it "crushes the growing threat of Mac malware," it pretends to be a comprehensive solution to protecting a Mac. This is deceptive nonsense. If you believe Malwarebytes' marketing, that all you need to protect your Mac from "malware" is their product, you have been badly, and deliberately misled. As much as I have respected Thomas Reed up to this point, this is a huge hit to his reputation. Frankly, I hope he goes back out on his own, because his contributions, buried deep in the company's website, are being wasted there. As to Mac users, we're stuck trying to protect ourselves with a myriad of products whose functions overlap, price points differ, and many of them saying they're the best and/or all you need. It's a mess with no end in sight.

This software is a total mess. It installs a global LaunchAgent, two LaunchDaemons, a kernel extension, lots of stuff in global Application Support. And even if you just want to use it as a freeware, the RTProtectionEngine is still working in the background, and it's taking up a lot of CPU power at times. Maybe it's just updating the AV rules, but for the freeware it would be completely sufficient for the RTProtectionEngine to be unloaded, lie dormant, and the rules are only updated when the user launches the main application. This thing is so bloated, I almost got a heart attack when looking at the pkg contents before first install.

I seriously suggest that those users, who just need a freeware manual scanning tool, uninstall version 3 and re-install the old version available here: https://data-cdn.mbamupdates.com/web/mbam-mac-1.3.1.dmg

This version (v1.3.1) is 64-bit, i.e. ready for 64bit-only macOS, currently updated for HighSierra support, it still receives the latest malware rules & definitions, albeit in a different format than version 3, and according to the developer, it will continue to be supported in the foreseeable future. Oh yeah, and it only installs one little helper tool. :)

@MacUpdate: you should add download links to the old version 1.x.x to the software description, not because of what I wrote, but because it might be useful for users running older operating systems.

They did a good job of commercialising a perfectly good product, the original product worked really well and i would have happily paid for it. Alas this is a monster just like the PC programs of a similar nature, Malwarebytes installs files in all sorts of areas of your system, and while it might uninstall itself via the program, it still leaves files in the protected areas of the drive, making removal an almost impossible task. A great shame IMHO as it will end up just like all the other subscription based anti-whatever programs.

This is another subscription based product which hides its actual cost until you reach the purchase page. This product now costs $40 a year for continuous protection, which means the product is running all the time like anti-virus software. Its product line seems to be primary focused on Windows. I did not see viruses mentioned on the website which leads me to believe that it does not replace such a product. Given that what it offers to protect you against is constantly changing it is a product that requires regular updates. While a subscription model makes more sense of a product like this than for a standard app, it still is like purchasing term life insurance If the company fails, or exits the Mac market your entire investment is lost.

This is not true. Malwarebytes for Mac still offers the same protection it always has - manual scanning and removal of detected threats - for free. The only thing that costs money is the real-time protection feature, which proactively protects against threats.

To Developer: What I said is true as I indicated that the subscription was for Continuous Protection. Continuous Protection is NOT manual scanning. that has to be enabled by the user for it to occur. The only place that I found mention of manual scanning available in the free version was in the pricing list that compares the different levels of the products. The reference on the home page only indicates the free version is capable "cleaning an infected Mac" which is quite vague in my opinion.

The other day I received a phone call from a person, a college professor of mathematics, I support who was quite upset because he did an update to the product and suddenly found it indicating it was now subscription based. In order to relieve his concerns, I made available a the version he had been using which had no such dialog. It took me close to ½ hour to calm him down as he was quite upset with me as I had initially recommended it to him and had no idea the operational paradigm had be switched.

If it was that confusing to him, I can only imagine how confusing it might be to others as not everyone is savvy enough to click on the pricing button to get to the detailed comparison where it indicates manual operation.

Additionally it states that it removes malware. However it does not define what malware is as 'malware' is a vague term. While it does mention adware, it fails to mention viruses, ransomware, key recorders, etc. So it leaves open the question will this product fully protect my machine or do I also need a virus checker and ransomware detector as well.

As such I stand by my comments.

If you, as the developer, don't understand our concerns, then this product is possibly even worse than we thought. We don't want constantly running "protection" that has not been vetted and may present its own attack vectors. We don't know what it is phoning home. We trusted the old Malwarebytes, but you prevented us from stopping the daemon(s?) from running, so we couldn't run this program safely. We understand that you are now being paid to add this "functionality" to the program, but did you ever think that on Macs, what the old Malwarebytes provided was what we really wanted (and needed)? At this time, for Macs, running a real-time malware interception program is not necessarily better.

Well, it had to happen. Malwarebytes is, after all, a commercial undertaking. They purchased and rebranded AdwareMedic to get a toehold in the Mac market. Now they have a "full featured" version, not unlike other commercial security programs. And, like most of the others, it runs on an annual license costing around $50. On a PC that cost is justifiable. On the Mac, not so much. For one thing, Sophos Home is still free. So when the 30 day trial ends I'll continue using the free version of Malwarebytes, thank you very much. FYI: A friend of mine was once again infected with that persistent Xfinity popup window. Malwarebytes didn't touch it. The freeware app Maintenance killed it. So stick with Maintenance or Onyx by the same developer.

The version number '3' of Malwarebytes Anti-Malware for Mac was chosen in order to provide numbering parity between the longer running Windows version and the more recent Mac version. Therefore, there is no version '2' for Mac.

He would have been perfect if the installer offered the possibility of not installing the extras. Having a anti-virus, they are more programs competing by the resources of mac. And it slows down everything.
In its previous version, it was a complement to the anti-virus that in addition does not overload anything, since it was executed manually. Even though also it installs a demon always working.

It works VERY differently than traditional anti-virus software, so shouldn't use as much processor time.

Regarding your question about uninstalling, please never remove ANY software by just searching for stuff using EasyFind, or something similar. There are plenty of apps that won't be properly removed using that technique. If you want to remove Malwarebytes 3.0, use the uninstaller that is on the same disk image file as the installer.

As a tech, I can tell you Malwarebytes is absolutely necessary! I see lots of personal Macs (and Windows laptops), and I can't tell you how often Malwarebytes (and Adware Medic before that) has identified adware or malware on that Mac.

All this can be done by hand by checking the folders where malware on Mac likes to install itself. (And I still do this on occasion for finding old software that are causing problems with the newer OS. But Malwarebytes certainly helps by automating much of this process with a quick scan.

Macs are still virus-free.
Malware and "viruses" are not the same things. Malware doesn't self-propagate. It's on your computer because you installed it, either by being mislead or by being silently included along with something else.
And I don't mean that with judgement. It's simply a fact.
Avoidance of malware is not a technological thing. It's about being suspicious of everything that comes into your computer. It's about "is it really a PDF?", "did my bank really send this to me?", "is this really a video codec for porn?". It's about going to adobe.com to get Adobe Reader or Flash Player rather than clicking a button because a page said to. It's about doing Google searches of everything you're going t install, with the word "malware" in the search, BEFORE you install it. MalwareBytes itself is not malware-prevention. It's a remover to clean up afterwards.

We need to be careful of taking a blanket position that avoidance of malware is mainly just a question of people not reading instructions carefully and exercising reasonable decision making when it comes to selecting Ok vs Cancel, or in general, the software we install, and where we get it from.

The users on this MacUpdate forum for the most are technically knowledgeable with far more computer experience than most, representing (just throwing out a figure) maybe 1/10 of one percent of the population. What seems 'obvious' to us, like "read the instructions', "only download direct from the developer's site', 'know your source', and so on, is NOT necessarily or always obvious to the other 99.9% of the general computer using population.

By its nature, malware (and I'm including in this crapware, bloatware and PUPs) is created and propagated with the intent to DECEIVE. There is no technical, moral or legal reason that any malware must advertise its presence, state its purpose in clear understandable language or even offer the opportunity to Install or Not install. That malware will always present itself with even the OPTION to not install itself is a very dangerous assumption.

@jamesdeanappleeater: brought up the example of his parents. everyone of us on this thread have family members or friends just like his parents, and we on this thread are probably the 'techie' person others in our family turned to when they have a problem. It is a bit naive IMO to make the case that if his parents (or just anyone of our own family or friends) simply READ the instructions, they wouldn't need to ask our help or be afraid to take action. again, I'm not making this about @jamesdeanappleeater's parents, you could fill in with any person we know in our lives that fit the same mold.

Just recently, Intego sent out a report of a new Mac malware that parades itself as a Flash update.
https://www.intego.com/mac-security-blog/fake-flash-player-update-infects-mac-with-scareware/
The software is even signed with a legit Apple signature. So it passes the Gatekeeper firewall. To the general population of computer users. it very closely mimics the same look, feel and procedures as a real Adobe flash update, using 'normal, simply English'. In this scenario, even after reading all the language, "reasonable people", like @jamesdeanappleeater's parents, might make the decision that they will not 'bother' to call the 'techie' in the family and ask if it is alright to proceed. And they will click 'OK'.

First of all, let me be clear, I am NOT in any way ridiculing his or anyones parents or making derogatory remarks. If anything, I am saying his parents are representative of many of my friends and family, and probably everyone reading this thread would say the same that they know people just like that.. People who have been shell shocked, warned not to do this or that on their computer, and conditioned by years of hearing about threats and viruses, and malware, stuff that at a technical level they don't really understand the difference, how it propogates, etc, that they are almost paralyzed with fear to do anything without first calling their son or the designated 'computer guy' in the family.

And you know what? that's OKAY with me that they keep coming to me and asking, because like this new Flash scam, they can read all the 'normal, simple English', and it all seems very clear and legit, and still be a total scam. And again, that even assumes that malware even offers the opportunity to refuse installation. There is NO technical reason that malware can't be installed silently as part of a larger install of what appears on the surface to be legit software. Once you enter your password, you have opened the door to whatever that install wants to do. For all the criticism about the Mac App Store, I for one believe it has done a great deal to reduce the risk of mailcious software. My wife is extremely intelligent, with a Master's Degree and successful professional career, but she is not a computer techie, and doesn't care to be, or want to be, or profess to be. Prior to MAS, she was always asking me, "is this program safe? is it okay if I buy and download it from this site?". After having been bitten too many times by crapware, malware, bogus ware, etc, she was paralyzed to do or install anything without consulting me. Now with MAS, thanks to the vetting process, the availability of reviews from REAL users, she now buys software on MAS, with much greater confidence, and I don't feel she needs to check with me every time she finds something she wants to try. Is MAS perfect? No. Can bad stuff still get through? Sure, but it it far better than no vetting process at all.

So, 1) don't assume that malware must always make its presence known and provide an opportunity to cancel installation; this is MALWARE people, it doesn't have to play by civilized rules. 2) like the Flash malware scam that's come out, don't assume that clear, simple instructions will always lead towards making the right decision. It's meant to deceive, and lay people who don't work with computers for a living, can be deceived.
3) because lay people can be deceived, never try to discourage them from coming to you when they are in doubt. Don't make them feel bad for coming to you or make them feel dumb. Believe me, it takes FAR MORE time to clean up an infection for them later than the little amount of time it would take if they had just stopped to ask you in the first place before proceeding with what turns out be mailcious.

This week it was discovered that copies of the popular program Transmission were infected with ransomware, named 'Keyranger'. It was embedded in the installer of what to all eyes was a legit, safe installer/program downloaded directly from the developer's site. The ransomware was code signed.

http://researchcenter.paloaltonetworks.com/2016/03/new-os-x-ransomware-keranger-infected-transmission-bittorrent-client-installer/

The argument stated in this thread that adware/crapware/malware can be avoided by carefully reading and researching what you install, and that people who get infected are people who can't read simple 'English', can't understand Install instructions and don't know the difference between OK and Cancel,...well that is totally wrong! There is no technical reason what happened with Transmission can't't happen again and again and again.

Malware doesn't have to advertise itself, it doesn't have to give you a choice to Ok or Cancel, it doesn't have to 'play by the rules'. It doesn't have to explain what it intends to do in simple, clear English. By nature, it is there to DECEIVE. You can argue the fault is the developers of Transmission for having lax security and allowing their app and web site to get compromised. To some degree yes, but are you willing to stand there and say I don't need to malware detection software because i TRUST the developers of the apps I use to secure their web sites, and their installers? In any software company, are you sure they have procedures to make sure maiicious code isn't being injected into the code base? Or maybe they are cocky and think, we're on Macs, who cares, it won't happen to us. Software these days can be THOUSANDS and MILLIONS of lines of code, no one person can understand it all. Whether by error or by intent, it wouldn't take much for malicious code to be introduced into any software package. Donwloading direct from a dev's web site isn't 100%j insurance, as the situation with Transmission clearly demonstrates.

This is life in the modern cyber world, no one is immune, not Linux, Mac, Windows, iOS, Android or xyz of the future. I;m not here to argue what product is best, worse, that's up to you, I'm just saying even if you think you practice 'safe computing', don't let your ego get in the way. anyone is vulnerable.

If you use Transmission, and upgraded to version 2.90, BE SURE TO READ THE ARTICLE AND GET THE UPDATE AND CHECK YOUR SYSTEM FOR KEYRANGER MALWARE. And by the way, as of this date, MalwareBytes did NOT detect Keyranger, either as part of the Transmission install package, or detect it after running the infected Transmission app. I tested it inside a Virtual machine just to see.

Yup,

I was lucky - I installed Transmission 2.90 before the download got infected.

Had I downloaded it a few days later, I could have become a victim to ransomware. PHEW!
Thankfully, I keep a lot of backups so I wouldn't have lost much by erasing the drive and cloning it from one of last night's.

The - what can only be nebulously referred to as - "logic" surrounding the Transmission breach is just plain fascinating. The thought process seems to be "since one app developer was breached severely in an extreme and highly unusual way, there's no point me ever paying any attention to what I'm putting onto my computer."
The Transmission breach was EXTRAORDINARY. It was accomplished by incorporating the malware into their source, which was then compiled and signed BY THEM inadvertently.
The real world analogy is that someone stole a real ID from your electricity/water/phone company, had plastic freaking surgery to look like them, showed up at your front door, you checked their ID and let them in. And then they stole your sh*t.
Do I have to say again how outright, flabbergastingly UNUSUAL the Transmission incident is?
Should you still check identifications before letting people into your house? Yes, of course you should. Are you going to just let in anyone because one time one thing happened once, and now doing anything sensible is just pointless? No, don't be utterly stupid.
And yet, people are determined that it means they bear no responsibility for what goes onto their computer the other 99.99999999999999999% of the time.
What it says is the exact opposite. It says that you need to be prepared for if/when even KNOWN REPUTABLE software goes rogue (e.g.: let's say uTorrent's sidebar becomes a vector for side-loading software into the main app or into your profile, or Google's Chrome Store gets breached and a compromised extension update goes out). You need to be vigilant and you need to have a backup.
Everything I've ever said is simple Digital/Online Stranger Danger, and it baffles me that people are determined to argue against basic common sense. Would you be alarmed if your child argued against what you teach them about real-world Stranger Danger? "But daddy, if a stranger might somehow miraculously guess the password anyway, there's no point me asking for it at all." Would you just not bother teaching them because, hey, even if you teach them well, some absolutely extraordinary "struck-by-lightning"/"won-the-lottery"-level unlikely confluence of circumstances might mean they're taken anyway?
And yes, NOW I'm moralizing. Because frankly, some people asked for it and deserve it.
To summarize: don't be an idiot. Treat entrants into your computer with at least the same caution as entrants into your house.

I don't think anyone is saying that just because the Transmission situation was unique and unusual that you don't need to be careful. I'm saying the exact OPPOSITE. I'm saying you can be careful, careless, smart, dumb, knowledgeable or ignorant and you can STilL have sh&t happen to you. Whether you are a computer 'expert' and practice 'safe computing', or a complete novice, there is no reason NOT to use Malware protection.

Okay, so the Transmission case was extraordinary and unique. Here's something just came out recently. It is not about a program that went rogue and was compromised at the source. It is about a new program created from scratch with no other purpose than to be malware.

https://www.intego.com/mac-security-blog/eleanor-is-dangerous-mac-malware-that-can-steal-data/?utm_medium=email&utm_source=security_alert&utm_campaign=security_alert_eleanor_20160707&utm_content=screenshot

At one point this was AVAILABLE ON MACUPDATE, until its true purpose became evident. We can ask, how did it get through gate keeper? Well, as I've been saying , there is no technical obstacle to creating a program like this File Converter 'app'. Anyone can register with Apple as a developer and provide enough info, bogus or otherwise, and obtain a valid signature. You can write a malware program, complete with valid signature, and get it posted in a dozen places, from MacUpdate to fake developer sites, 'industry review' sites, that look very legit etc.

By the time anyone realizes its malware, there is little chance of catching the culprit. There are dozens of ISV developers right now working out of Russia, Eastern and Central Europe, all producing perfectly code signed software. Fortunately, the vast majority are hard working, honest ISVs. But what would prevent any of them from suddenly turning out malicious software, either intentionally or by being compromised, like Transmission was. Again, this File Converter malware recently discovered, there is no technical reason why another situation like that can't be repeated over and over again, code signed or not.

Now we can argue all we want about how people need to be careful, use common sense, treat software like you would a stranger coming to your door (all of which I agree with), but you will still have people that get bit. People aren't supposed to get accidentally shot either if they are careful, but still people do.

When bad things happen to good people, it doesn't necessarily make these people stupid or idiots, and we shouldn't make such blanket conclusions. We have to remember, what is obvious to us on this forum as the top 1/10 of one percent who are computer knowledgeable and experienced, is not necessarily obvious to the other 99.9%. Now you can argue all you want that the people who downloaded the File Converter malware program should have been more careful, okay if you take that position, then no one would ever try ANY new program.. Every new program on the market MIGHT be malware, just like this File Converter app. After all, when a new software company starts up , or new apps come out, what does ANYONE really know about them or the program? At some point, somebody has to be the first to try it. Like the old days when monarchs would get assassinated by being poisoned. Bring in the food taster, let him eat it, if he is still standing after five minutes, then I'll eat.
Well, Malwarebytes is my 'food taster'!

My wife has a Masters Degree, a very successful professional career, and is very smart. No one would dare call her ignorant, stupid or carelless BUT she is not a techie, doesn't want to be, doesn't care to be, doesn't have the time to become one. Fortunately she has me to ask "is this program okay? Is this legit?" Is this a scam?" But some people don't have that person in their lives, and even if they do, I can't be there to protect her every second. For all the hate that people have against the App Store, one thing it has done is provide a first line of defense against crapware and malware. My wife is so much more confident now making her own software decisions and buying programs on MAS, being able to read reviews from other uses and so on. It has liberated her from being totally dependent on me to make decisions for her about what to buy. MAS isn't perfect and can't protect against everything, let alone just plain software that doesn't work well, (not malicious, but just plain sucks), but it's SOMETHING.

We can agree to disagree on whether avoiding malware or viruses is just a matter of common sense or being prudent, and people should be more careful and so on and all of that can be true, and even if we agree some people are just plain dumb and got themselves into trouble, that's still no reason not to recommend that people use antivirus and anti malware protection. Because careful and smart people still get hurt sometimes.

Life is full of things we have put in place to save people from themselves, from their own carelessness, ignorance or stupidity. We have safety locks on guns, child locks on car doors, and dead bolts on our front doors, and yet people still get accidentally shot, children still get hurt in cars, and people still get their homes broken into. Do we take away people's guns, cars and homes cause they might be dumb or careless that one time, no of course not.

My error, the File Convert app was not code signed. So yes, i was wrong about that, but still doesn't change my argument. A lot of people run with Gatekeeper off. And my point that someone can still write malware AND code sign it, is still true. It's not that hard to get a signature.

I have seen a report that Snort (used by some AV software to filter network connections) has a rule that is triggering on our user-agent string. (This is a string sent to web servers to identify the browser.) This would appear to be triggering because our user-agent string, which begins with "Malwarebytes," contains the word "malware."

We have attempted to contact the folks behind Snort, but have yet to receive a response.

This works very well. It finds and removes adware and developer has done a great job of keeping it up to date. Because of how some of the adware tries to hide, AdwareMedic may need to be run multiple times. This does not protect against adware, but it's not designed to do that. You can still get infected from adware if you get something from download.com for example. This is just the easiest and cleanest way to get rid of it once it's on your Mac. Read the developer's article at http://www.thesafemac.com/mmg-defense/ to better understand how to avoid adware in the first place.

I've never felt an urge to leave a review before but Adware Medic impressed me so much that I went ahead and made an account on this site just to leave a review. It all began when I started getting pop-ups from random websites. A few minutes after that, I was prompted to download Flash. Knowing that Flash is a regular necessity, I downloaded it blindingly, thinking that it might have something to do with the website i was trying to access at the time. In retrospect, it might have been a disguise or something because it downloaded two strange apps called MacKeeper and another one that I forgot the name of (deleted it at first sight). Then it really started to bother me when I searched for something on Chrome and it redirected to search-quick and then to thesmartsearch. In my four years of owning this Macbook, I've never had this experience ever. I checked my Chrome settings and everything was fine: the default search engine was Google and the extensions were clean of suspicion. Worried, I browsed through existing apple threads concerning 'thesmartsearch' and found AdwareMedic. This app solved my problem within less than 5 minutes. I downloaded it, did a scan, clicked the fix button, restarted and everything was back to the way it was! Perfect condition! I am mindblown and exceedingly impressed! Thank you so much for such an amazing and free software!!!
