Technical Details

This program is the "demo" version of a rogue antispyware application. It attempts to convince the user to "upgrade" and purchase the full version of the software by making the user believe that their computer system is riddled with malware; the malware would, of course, only be removed if the user purchases the full version of the program.See also the rogue antispyware description.


Upon execution, this rogue antispyware displays this End User License Agreement (EULA):

Supposedly, the user must accept it before the software will install onto the system. If the user does not accept the EULA, it will not pretend to scan the system and display fake output. It will, however, still create the following registry keys:

  • HKLM\Software\VirusRemover2008
  • HKLM\Software\{5222008A-DD62-49c7-A735-7BD18ECC7350}

Create these files:

  • C:\Documents and Settings\All Users\Start Menu\Programs\VirusRemover2008\VirusRemover2008.lnk Link to C:\Program Files\VirusRemover2008\VRM2008.exe
  • C:\Documents and Settings\%current user%\Application Data\VirusRemover2008\Logs\scns.log Contains a log of requests sent to
  • C:\Documents and Settings\%current user%\Application Data\Microsoft\Internet Explorer\Quick Launch\VirusRemover2008.lnk Link to C:\Program Files\VirusRemover2008\VRM2008.exe
  • C:\Documents and Settings\%current user%\Desktop\VirusRemover2008.lnk Link to C:\Program Files\VirusRemover2008\VRM2008.exe
  • C:\Program Files\VirusRemover2008\Viruses.bdt A text file containing the list of the fake malware found in the system.
  • C:\Program Files\VirusRemover2008\VRM2008.exe Main rogue scanner file detected as Rogue:W32/VirusRemover2008.C

It queries this website:


If the user does agree to the EULA, the program does all the above, and in addition will pretend to scan the system:

After the scan, it will display these files, which are supposedly on the computer system. In reality, these files are taken from a predefined list located in C:\Program Files\VirusRemover2008\Viruses.bdt.

If the user closes this window, the rogue will display this notification box to remind the user that the system is still infected:
