Another Win32 trojan-gen that creates a random 4letterfolder in C:\Windows\temp that sometimes contain a fake Win32 trojan-gen svchost.exe file.

Avast5 puts it in the chest all the time but it keeps appearing so something else is responsible for its reappearance.

I have tried "The Avenger" for rootkits
I have tried Systemlook with no avail.
I have done daily searches with MBAM
Done daily searches and full protection with Avast! 5.

Still, I can't find the SOURCE of the virus reappearance.

Please help me solve this painful riddle.
