    Thank you, this is just what has happened to me! -This annoying little pop-up warning me for a high-risk trojan which will steel my personal passwords and other stuff.

    I’m a rookie, so I almost believed it and I was just about to download Personal Defender 2009 when I got alittle suspicious. -Lucky me :)

    So, thank you!

    hey thank you for the fix for this. I new it wasn’t windows when you read that message and they misspelled “your computer” and put “tour computer” i knew windows wouldn’t put out anything that was misspelled. Also it took down my firewall when i first saw the message then windows security (the real one) poped up to tell me that my firewall was turned off. Thanks again for the fix

  4. Pete

    Hey, thanks.

    When i try to set up Malware the installation stop and freeze, so I can not complete the installation, and remove the virus. :(

    Anyone can help?

    I downloaded it but then uninstalled it, it went away with absolutely no trouble and I see no remnants of it on my computer. But it must have already infected me because AVG is saying I’ve got a high risk keylogger, after scanning, it says there are changing to a bunch of system32 garbage, my malware won’t open, all legit antivirus sites are firewalled automatically for some reason, and I keep getting this “Enable protection” pop up.

    I’ve tried what you suggested but nothing will execute. The program refuses to run, like all my other spyware.

    I suspect that Malwarebytes’ Anti-Malware (mbam-setup.exe) – may be the REAL FAKE.

    None of these companies can be trusted.

    Also … could you people learn to spell!? What has happend to this country’s very very basic education program!?

  7. jojo

    … sorry .. mis-spelled “happened”!

    I discovered a new variant tonight on a friend’s machine. Looking in the registry, it referred to an apparently random directory name in the user profile. The EXE also appeared to have a short random alphabetic name. Malwarebytes said it removed it, but it came right back on the next reboot. I dug into the registry and ripped out the keys, and found and deleted the files.

    After removing it and rebooting, the infection appeared to be gone, but IE wouldn’t display any web pages, although the internet would connect and there was data traffic. The reason it wouldn’t display any web pages was that the browser connection settings had been modified to point to a proxy server at, which I believe means that a web server had been installed on the computer and was intended to act as a proxy for all web pages, possibly scanning them for important information such as userid’s and passwords and then sending that information to a remote recipient. I don’t know if the web server was installed to a different location from the Personal Defender EXE; it is possible that it was, because I could see traffic even though there were no programs that I knew of that were using the web, even in the background. Possibly the configuration was faulty and the web server didn’t function properly, and this is why I noticed it. I believe that IF it functioned correctly, then I would have believed the infection was gone, while a very insidious part of it remained, silently siphoning off userid’s and passwords for websites.

    After you have cleaned up the infection, be sure to check your browser’s connection settings and verify that it does not point to a proxy server at

    To clear up this part of the infection I used a system restore point to two days prior.

    Good luck with particularly nasty infection.
