MacDefenderKiller is a trojan removal program, which is used to remove a few strains of the "MacDefender" trojan horse that is infecting Mac computers as of 2011. Read all about the virus at http://www.businessinsider.com/mac-defender-virus-scanner. Our software seeks out the MacDefender app, related MacDefender downloads, the MacDefender login item, MacDefender running process and kills them. We don't require a system password to use and can be run from a flash drive if needed. This also works with a few of the other strains of the MacDefender virus. We also patch the "Open Safe Files" option in Safari so the virus cannot more...

  • Will now remove any of the MacDefender/Protector/Security/Guard installers at program start even if the malware has not been installed yet

Does MacDefenderKiller catch the new MacGuard variant?

ClamXAV has been updated to catch these new malware variants. Do yourself a favor. Install ClamXAV and be done with it. Whether these current variants are dangerous (even if they just hit your wallet) or not, it pays to have some level of protection in place. Can't get any bettern than ClamXAV...free, highly supported, and as uninstrusive as any antivirus solution can be.

IMO, a significant drawback to ClamXav is that you can't specify the entire hard disk for scanning. This makes setting up a scan more difficult for the novice user. Yes, there is a workaround (which is detailed in the FAQ at ClamXav.com). Regardless, it's not as simple to use as the alternatives. If free is your goal, however, it certainly does the job without any financial cost.

ClamXAV can catch MacDefender and the several variants that are floating around. If a virus/trojan/malware hits the wild, the opensource community doesn't waste any time updating defs. ClamXAV was one of the first (if not the first) to protect against it.

You're essentially saying that same thing that you said the first time around.

The point of my posting is that despite the advantages of open source software, there are still sometimes notable disadvantages. In the case of ClamXav there is a significant U.I. flaw, which prevents it from being suitable for everyone.

Because of this, I hesitate to recommend it across the board in my Mac consulting business.

I agree with the previous comment - but people are dumb enough to install MacDefender/MacSecurity. From what I've seen so far it's been limited to Firefox users acknowledging the "you're infected!" warnings. Must be a plugin thing, I don't know - I don't use Firefox.

First step, ditch Firefox. Second, run this MacDefender app (though I doubt anyone gullible enough to get infected would actually browse MacUpdate.com, let alone know what to do)

I hope Apple releases an update targeting this nuisance, I've seen an 'infection' already, plus two of the "Infected!" warnings on others.

Thankfully this phishware isn't malicious, but I suspect this is just the beginning.

Safe browsing all.

If you're a Safari-user, it's having -Defender/-Security installed in the first place that CAUSES you to get the infection "warnings"! It also locks your browser onto that page, forcing a restart to get away. And, of course, it may take over your browser again, at any random moment after the restart, although it appears to be more likely to strike, if you're surfing porn, the point being, no doubt, that porn sites often try to keep you from leaving them, unless you first click on a four-inches-more-dick ad, so that a cookie can be set. So, when the virus strikes, it appears to be trickeration coming from the porn site and not from your own fucking Mac. The "Warning" screen itself is straight out of Windoze. There's nothing that could possibly induce a Mac-user to click on any of its links, except, possibly, hubris: "I'm using a MAC, asshole! I can click on any link on this page and nothing will happen!"
I had ClimXav installed. It was perfectly content to let me download and install -Defender. (Mac sites have been alive with shouts of "Trojan!" So, having a little extra help seemed like a good idea, at the time.) Then, I installed (the free, Mac-compatible version of) Sophos. It immediately eliminated -Defender. Then, -Security was released. The icon had a familiar ring to it. The familiarity is explained by the fact that the two versions of the virus share an icon. But, when you're in your mid-seventies,
senior moments happen. However, as soon as its FOLDER appeared on my desktop, Sophos was on it like a housecat on a housefly. I could have forced Sophos to allow me to install it, anyway, of course. But, not even we elderly are as stupid as that.
BTW, I'm not trying to say that Climax isn't up to the task. I may have mis-installed it. Who knows? My main point is,

Be careful! It's a jungle out there!

Longboy, that really isn't appropriate. This isn't an adult website and this isn't your mother's basement.

Longboy, your profane rant is a complete waste of everyone's time, for you say nothing worth reading. Please restrict your replies to one sentence until you have confirmation from at least 3 other people that your thoughts are constructive.

If people were dumb enough to install this MacDefender trojan, I guess they never visit any Mac websites, like this one, their knowledge about computer are limited, to say the least, and they are not even aware of the problem...
Anyway, thanks for helping and posting this tool.
