Downloader.MisleadApp Infestation

Morning all.

 

So, as the subject says I have been hit with the Downloader.MisleadApp trojan. I have tried a number of things to get this nasty little bugger off my machine (short of nuking the hard drive), but it's still beating me. Here are the things I've tried ...

 

- Updated the virus defs for Symantec AV, but when I run a ful system scan SAV doesn't nothing. It will just sit there on the scanning screen, but will not scan any files (total scanned files: 0) ... This ran for 24 hours for I ended it.

 

-  I attempted to run Ad-Aware, but it does the same as SAV.

 

- I attempted to run Spybot S&D, but it would not launch. Uninstalled it and when I attempted to reinstall it, my computer would blue screen.

 

-  Trend Micro HijackThis, but the application will not launch.

 

- Attempted to install Malwarebytes Anti-Malware, but it would blue screen my computer when it was just about finished.

 

- Attempted to run ComboFix.exe, but this will not launch.

 

- Attempted to install SUPERAntiSpyware, but this would not install either.

 

(all application that would not install were renamed, but didn't help)

 

- I also used a few different online virus scanners, but they would scan for a very long time (more then 12 hours). 

 

Is there anything that I can other than reformat/reinstall? I know this is the best way to go, but reinstalling everything is such a pain in the butt. lol
