Reliable antivirus with powerful anti-malware protection

MacUpdate Admin: you keep posting a version as 'new' that came out a while back as of 3026-21

The App seems stable on both a Mojave iMac Pro, and a Catalina iMac. However, getting responses from their Tech Support is a real problem. They used to respond quickly, but I have now been waiting several weeks!

This installs an unquitable service. When asked for an option to fully exit their software, the company has repeatedly dodged the question and refused to do so. They only tell you how to hide the menu process not exit the background agent. This is extreamly shady behavior. Malwarebytes used to be the goto for anti malware, but I have no choice but to believe they may be snooping on you and your system to sell your data. This is the only reason to respond the way they have. As a sysadmin, I cannot tolerate a piece of software that inserts itself without a way to disable it completely. If the agent becomes infected, has a memory leak, causes an incompatibility that creates a kernel panic, There is no recourse. Malwarebytes now insists on behaving in the same manner as the software they were designed to protect you against. Use something else.

Existing software on your system loaded a system extension signed by “Malwarebytes Corporation” which will be incompatible with a future version of macOS. Contact the developer for support. (From Apple...)

I've been a Mac user since 1993 but I worked with DOS, OS/2, and Windows machines for years. The typical anti-virus software wasn't good enough. A few years ago, I got a touch screen Windows machine to try, and ended up buying Malwarebytes because it was really amazing at keeping the machine clean. Coming back to an older Mac running Catalina, I needed good software to eliminate threats. Sophos anti-virus wasn't helping on a previous machine, and situations were becoming more intense. I needed software that didn't work the same old way. I needed software that looked at more intricate patterns that would end up in a compromised system--to stop what was happening. Malwarebytes is that software. It's useful to buy a multi-machine license, if you're using multiple Macs or Macs and Windows. Obviously, my mid-2012 MacBook Pro is hardly new, but the software hasn't produced a noticeable slowdown.

Wow, it installs a menubar menu item without my permission suddenly today. Not cool. Then I find out it has lots of problems with 10.14.6. Complex steps needed to get it to work right under 10.14.6. It took over my computer without warning this morning. Removing the app, they failed to respect my computer.

Sits quietly In the background of my iMac Doing nothing wrong really. It has on occasion caught Mac Malware, quarantined, repaired, and deleted It. Very good program.

1/17/2020 - Using Malwarebytes on Mac OS 10.15.2 causes internet to not download data with a "Connection error! The request timed out." dialog to appear. Removing MB returns everything back to normal operation. On reinstallation of MB problem returns. (2013 MacPro 6,1)

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.

finds among my (over 300) clients about 1500 inf. per month

What's going on? On Aug 1st, I downloaded & installed v. 3.9.23.2814; now, just 8 days later, they issue 3.8.17.2526. Are they backtracking??

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.

Well, its good to know that I am not the only one and I hide my login also. I think it is very easy to use and I am happy with it so far. Thanks! <a href="https://www.filehippoz.com/filehippo-malwarebytes-free-download/">Malwarebytes</a>

Malwarebytes deserves a better review. You can still use it for free; you just have to launch it manually. The paid version can be scheduled to work, if you need that much protection.

Thanks for sharing this article. I really found it very helpful and interesting while reading. Nice post. <a href="https://www.filehorsee.com/filehippo-malwarebytes-free-download/">Malwarebytes</a>

drives my powerbook fans crazy

Too many different applications claim basic protections and overlapping options I prefer having a complete software rather than several software packages.

It kept deleting my other spy, & adware

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.

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.

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.

I downloaded and installed version 3.3.22. No problem with ClamXAV. Works well, it did fine som Malware occasionally I use macOS High Sierra on a Mac Pro Mid 2012 I did a scan and nothing bad was found.

This latest version, 3.3.22.1387 failed to install. Mac os 10.11.6

$40 for each Mac I own???!!!

Just installed 3.2.36, even tho the app shows 3.2 on a Get Info.

If you single click on the app in your Applications folder it shows version 3.2. But if you do "About Malwarebytes" it shows version 3.2.35. You would think they would put this as the version seen from the Applications Folder.

I tried to install the new version. I got a warning that the installation failed and to contact the software manufacturer for assistance. Anyone have an help?

Malwarebytes for Mac is the only Malware program you'll need, as long as you are running pro. It's so easy to install and boot a virus on Mac... It's sad!

I've been using it fro a while. It seem to really protect my mac from malware.

Excellent! Only problem is that it claims one of my favorite anti-virus apps is malware...and that app returns the favor. What can I say? Neither is malware so I ignore both of their claims for one and another and continue using both.

I downloaded and installed version 3.2. ClamXAV did not put it in the trash automatically as it did before. I did a scan and nothing bad was found.

When I download Malwarebytes from either MacUpdate, or directly from www.malwarebytes.com/mac/, I get a warning from ClamXav saying, "Infection Found! Malwarebytes-Mac-3.2.35.1162.pkg infected with Trojan.OSX.BitcoinMinor" Should I worry?

Works good on PC. Gonna test it on my Mac also

Adware Medic in the new wrap does what it claims to do. For those who has doubts about this product check Apple Support Communities and users' feedbacks there.

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.

MalWare Bytes reports that Macupdate website itself may be infecting computers: "The malware was spread via hack of the MacUpdate site, which was distributing maliciously-modified copies of the Firefox, OnyX, and Deeper applications." From Feb 3, 2018 Macintouch report. What does Macupdate say. I'm a longtime MU subscriber and now worry that my Mac is at risk. I'm hoping the site monitors don't just delete this post without a response.

You can not Whitelist items! It keeps removing a valid Safari extension because its name looks like a known malware! That is bad...

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.

Terrible! Acts like a malware to your mac, by hogging your boot time. I tried to remove it from the login items list, but isn't present! It's embedded itself deep into the system and there's no setting to disable it. I'm also unable to remove the ugly logo from the menu bar (the settings to do so has no effect!). This app was great in the past, but not anymore! In the trash it goes!

Tallyho

The current version is 3.1.1.505

It is a monster memory eater. I have noticed some slowdowns on my iMac with 24gb of memory, opened Activity Monitor and found this http://d.pr/i/1S0Ygx After some period of time MalwareBytes running mad on memory. Uninstalled

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.

It was great. But now, goodbye.

Count me among those disappointed with the functionality of this version and missing the prior version. This version seems to use a lot of resources, has a background process that runs all the time (and can't be turned off), and seems to increase the overall memory footprint of my system.

It's been uninstalled.

Unable to disable the trial version. Unable to totally remove all remnants. Unable to justify "renting" software. Refusing to be tethered to a live internet connection, especially after all the issues with Drive Genius v5.x! Suggestions: Use Pacifist or others to determine where every piece of this invasive software has been placed. Consider an easily erasable partition or volume for the experiment. Too bad the original developer after selling his company now has a new master that seems a little too Micro$oftian.

Alas, all good things come to an end. Making money is OK. But why don't they offer their traditional non-automated version for a small $10 or $15 fee?

Wish I'd read these comments before trying this out. I used EasyFind to locate any instance of the term "malware" on my computer. I then manually deleted anything related to MalwareBytes. EasyFind seemed to find a lot. It's annoying, but I think the search was thorough. https://www.macupdate.com/app/mac/11076/easyfind

The instructions on how to disable the trial version of MWB and have it run in free mode do not work on the Mac. This needs to be addressed ASAP.

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.

DANGEROUS - DO NOT INSTALL! This software completely ruined a healthy Mac running Sierra. I installed it, but didn't like that it had hidden daemons running. So I uninstalled, but it never completed. Now I can't even shut down my Mac because "Other installations aren't complete" and I can't install or uninstall this software. This is the worst problem I've had in 25 years of using Macs. BE CAREFUL.

With the exception of MacKeeper, this is the worst review I've ever written for Mac software. I used to use this before the crazy installer. It ruined all of my Little Snitch rules, and I still haven't figured out what else.

The current version is 3.0.1.389. It provides a 30 day trial of the Premium version. After the trial, it reverts to the 'Free' version which provides malware removal with no frills. The Premium version goes for $40 and provides a one year subscription with these features: • Prevents Mac virus, spyware, and malware infections • Proactively blocks adware and unwanted programs [aka 'PUPs'] • Updates to the latest Malwarebytes protection automatically • 10 licenses. Business (99 licenses) and Enterprise (unlimited licenses) versions are available as well.

I'm confused. First, they say that the version number jumped from 1.2.6 to 3.0, then they say the software was previously called "AdwareMedic". Well, I HAVE AdwareMedic installed on my iMac and it is version 2.2.7. What is the true story here?

Nice! Pity the app crashes on High Sierra beta 5. Deamon seems to continue working...

I'm not sure whether I need this as I run Sophos which also claims to find Trojans, AdWare and the like. Advice anyone?

RIP, my lovely boy! It's NOT free from nowadays! 30-days trial, payed subscriptions and others sh$t..... :( Build number - 3.0.1.389

Fast! It found remnants of programs that have potentially caused problems in the past. Malwarebytes has made excellent scanners for years. This one scans and removes. Impressive!

Efficace et pas cher

trustworthy, reliable, effective

Fast. Easy. Perfect.

Malwarebytes detected mPlayerX (https://www.macupdate.com/app/mac/33261/mplayerx) as a malware. And there is no explanation. What is wrong with it?

Great Help

perfect little tool

Thanks, it just saved my and my Macs life!!

Simple and effective.

One of the best apps I've ever used on a PC and now it works on Mac's too! FANTASTIC!!!

Found two pieces of adware on my Mac and none on my other one. Just about to try my laptop. To use as a simple app, run it from the disk image and ignore requests to install. Then click on the Scan button. It even removes the adware to the Trash. Just remember to remove from any back-ups in Time Machine as well (handraulically).

Not 100% sure such tool is needed for OS X - nevertheless it can't be wrong to check it out for free. :)

Should be installed on every Mac connected to the Internet, it's simply that good at what it does. Been using it since it was AdwareMedic and I even donated to the developer back when it was independent, as it has saved me hours and hours of time cleaning up other people's machines.

Dead link, here is the correct link;
https://data-cdn.mbamupdates.com/web/MBAM-Mac-1.0.2.8.dmg

I've been saying for years to my pc friends: "no virus on mac, buy a mac!"... ;-) Yesterday, I've tried Malwarebytes, convinced that it would not find anything... and it found searchtab.safariextz, a Safari extension — probably not very harmful. After some googling, I can't be sure what installed it, but now I know the happy days of virus free Macs are over. :-/ Thanks Malwarebytes! :-)

https://mbam-mac-dl.malwarebytes.org/MBAM-Mac-1.0.2.8.dmg

Attention MU: As of today -- 08-10-15 -- the download links to version 1.0.1.7, and not to 1.0.2.8 as it should.

Works flawlessly and is an excellent product. I would highly recommend this product.

Turned off Firewall to test. Same problem exists.

When starting Malwarebytes 1.0.1.7, I get the following message Unable to check for newer signatures, due to a network error. You can use this app without updating signatures, but should be aware the signatures may be outdated. If you are using an outgoing firewall, such as Little Snitch, be sure to allow this app to connect to www.malwarebytes.com. My internet connection is fine. Looks like a problem on Malwarebytes end.

The download link doesn't work - either here at MacUpdate, or at the developers website.

Revealed OSX.CoinThief that was sitting ~1.5yrs in my System. A commercial AV I used after I lost several BTC didn't find it and it was a mystery how I was hacked until NOW. THANK YOU Malwarebytes

Congratulations to Thomas on his new partnership with Malwarebytes. AdwareMedic and now the new MBAM for Mac are simple, lightweight programs that can be trusted to do only what's needed without compromising your system. MBAM has been one of the most useful, necessary and trustworthy tools on the Windows side for many years, and as more and more users continue turning to the Mac and OS X, and as more websites rely on 3rd-party ad providers to create revenue, tools like MBAM unfortunately become more important to users.

AdwareMedic ?

Fast, Free & Effective.

Works great!

Does the job in seconds!

For some reason MacUpdate Desktop does not install this item. This happened for this and the previous version. I have to do it manually.

The best Adware Remover for OS X.

Superb. And free. Don't forget to stop by his two websites: the homepage for AdwareMedic, http://adwaremedic.com, and TheSafeMac, http://thesafemac.com, which delves into vulnerabilities and the complete and utter blight that is the trash of "cleaner" apps like CleanMyMac, MacKeeper and their abominable, useless ilk. If you're a Mac admin, take a look at JAMF Nation for a script to create an Extension Attribute in Casper Suite. Every time your Mac do an inventory scan, they'll report whether they've got Adware crap on them, and you can create reports, Smart Groups and proactively take action.

The best utility app ever!!! Infected by this crap of Genieo, I didn't knew this jewel and had to make a clean install. Infected again one year ago, (I don't remember the malware, perhaps MacKeeper), I found this great app, and it saves me for a new clean install.

Actually the only malware remover that worked for my annoying searchbar etc. THANKS! Sorry for not donating, if i was old enough i would.

Great app that does what it says without installing loads of crap, like some others do. This should have a price, but it comes free. Time to make a small donation to the dev.

Fantastic! Thank you very much for a wonderful application :-)

Fixed my issues quickly and easily. Thanks. Just donated. Ken

Fantastic, Saved me from a world of trouble.

this really works!!!!! i created a profile just to leave a comment on how great this app is. at first i was iffy about it but when i downloaded it the adwares were instantly gone literally

AMAZING!!! Saved me from my major panic about having installed something bad onto my brand new MacBook - thank you thank you thank you thank you!

Thank you SO SO SO MUCH!

I am so grateful for this application! Several months ago I used a site that provided free movie streaming. My computer life has been pure misery ever since - inundated with persistent popup ads and all manner of other intrusive junk that just took over Safari web browser on my Mac. No matter what I tried I could not get rid of them....until this free software! to which I owe my sanity!! I will definitely buy the desktop version and make a donation. It is so worth every penny. Thank you, thank you to the developers!
