Okay...keep getting "bad image" messages. Three different types: companion.exe, waol.exe, nmain.exe. These error windows have completely disabled my operational abilities. I cannot run software, virus check, disk cleanup, defrag - nothing. The message is always something to the effect of: The application or DLL c:\windows/System32\SENSAPI.dll is not a valid Windows image. Please check against your installation diskette. It isn't Bugbear...I've already tried that per a support engineer. Please help! I'm dead in the water over here.

I believe that the file companion exe is Spyware.So i suggest you install a spyware remover such as Ad-ware,or Spybot,If you dont have one allready.If you do?scan your system in safe to clean up the spyware.... http://www.majorgeeks.com/download506.html You can download spybot ,and Ad_ware at this link.After your system is clean of spyware,i suggest you install Spyblaster,and Spywareguard as spyware preventors. The file nmain.exe, i believe is a virus.here is info.... The bugbear virus worm spreads via shared network folders and through email. It can also terminate common antivirus programs. Once it has done this it is able to record and send out system passwords and logged keystrokes – all of which compromise security on infected machines. Also Known As: W32/Bugbear-A, WORM_BUGBEAR.A, I-Worm.Tanatos, Win32.Bugbear, W32/Bugbear@MM, Tanatos, W32/Bugbear Attachment: Nvc95.exe Nupgrade.exe Normist.exe (Nmain.exe) Nisum.exe Navwnt.exe Navw32.exe Navnt.exe Navlu32.exe Navapw32.exe N32scanw.exe .there is a alot more attachments,to many to list. To remove it,try to scan with your antivirus software in safe mode to see if it can clean it up.If not,Try http://housecall.trendmicro.com/ The waol.exe file you can read info here.. http://support.microsoft.com/default.aspx?scid=kb;EN-US;318352 Hope this helps?Peace
