    Nice to know that’s something easy to remove.

     Thanks Michael, you saved my life with this one!

  • Michael Steeber

     Your welcome. Always glad to help.

    Please remember that this not a virus…it is a Trojan horse. A virus will propagate automatically without user interaction. (There are zero viruses in the wild for the Mac.) This particular Trojan horse uses social engineering (in this case fear) to trick the unsuspecting user into entering personal finacial information which can then be used by someone else.

     Can we use the proper terms here?  As Apsco points out, it’s a Trojan not a virus.  More to the point, it’s not Malware it’s IdiotWare.  It doesn’t attack OS X, it attacks idiots using OS X.  Nobody blamed Microsoft when all those idiots kept opening up alleged naked pictures of Anna Kournikova, and likewise, this isn’t an Apple problem.  It’s an Idiot problem.

     lolz? It even has an installer? So it’s not really a virus or whatever. youe ven need to click through the installer to get it! then it’s your own fault! every 10 yr old kid could write a “virus” for mac os x if that’s what you consider a virus lol.

    This Mac OS X Malware occurred because Apple was sitting on its laurel claiming that its OS
    was impenetrable. I personally use Microsoft Security Essentials on my Windows XP machine an it works like the Great Wall of China. No Apple security application can beat that. This is one of reasons why I have a great website.

    Nice video…and thanks for spelling out the steps for people who are wondering what to do about the MacDefender thing. There are so many incomplete and unclear articles out there about this, it’s nice to see one that is complete and clearly put together. 

    Unfortunately though, the main problem is that so many users will fall for all these moronic scams…will click on anything that says “VIRUS!!!!”…and there’s not much any of us can do to  help them.

  • Ryan Warner

     Yeah, that stops it from running. I hate when any app leaves stuff behind, though. I tested this uninstall myself on a test machine I have. You might want to update this with instructions on how to delete these last 2 things:
    ~/Library/Preferences/com.aple.sv.plist~/Library/Caches/com.aple.sv.plist/

  • Ryan Warner

    Ugh. Obviously those two things should be on two separate lines. No previewing before posting, no editing of a post. That stinks…

     I also just found 3 .txt files in the user folder hat I guess it uses as a reference to show you your machine and app stats.

    dmem.txt
    hwuuid.txt
    proc.txt

    great video
    thanks!

  • randy

    Great video, thanks!  You showed how to change settings on Safari to protect from future problems with mac defender, any similar protection advice you can give for us Firefox users?
    Thanks again.
