In a nutshell, when I log in I get this fake anti-virus scan by "Essential Cleaner" that only takes 30 seconds (a real scan takes an hour) that finds "36 viruses." At that point, I get popup reminders that I'm infected, memory errors, and eventually BSOD.
I booted into safe mode and ran rkill (thanks for those who posted about rkill in the yahoo post above) and it noted issues with:
Rkill was run on 05/06/2011 at 19:09:39.
Operating System: Windows Vista Home Premium
Processes terminated by Rkill or while it was running:
Rkill completed on 05/06/2011 at 19:09:43
Even after running rkill, neither Malware Bytes nor AVG found the malware. The original poster above said he manually deleted the infected files, but this doesn't seem like a good idea. The two files mentioned in the rkill logged are date stamped 1/20/08, so I worry about these being necessary system files that are just infected.
Any thoughts anyone? In the meantime, I may try the other scanner utilities mentioned in the yahoo post.
