I was about to post a question regarding the Pontoeb.A virus i'd picked up on my Windows 7 install. MS Security Essentials detected it, and cleaned it ok, but ever time I rebooted my PC, Security Essentials detected it again, and an install would start for the "AV VCS Voice Changer" software. I spent a while looking in msconfig to find how this voice changer software was running on startup, and couldn't work it out for the life of me. After a few days though, something caught my eye...a startup item called AUDIOHD, with an unknown vendor. It was running a file called SystemDriver.exe, which would create another file called file.exe in my AppData directory. Of course calling itself audiohd was fooling me, i skipped straight past it the first few times thinking it was a valid driver. Anyway, I found the relevant registry entries and deleted them, rebooted, and sure enough no more Pontoeb.A I've found very little info on this via Google/Bing, so wanted to post it here in case anyone else has this issue.
