I don't know how I got the AV.exe virus & saw it coming onto my computer (running Win XP) last night but my AV (AVG9 - paid version) didn't detect or stop it. I thought I'd caught it & quarantined it but I now think that was the virus itself tricking me with a false message.
Most of the removal instructions I found said I'd need a different
computer to download the anti-malware software. I don't have
another computer. I got rid of it by rebooting my computer in 'Safe mode with networking' (hit F8 as soon as the computer starts to boot up). Then I did a 'System Restore' to the day before
the virus installed itself. The restore restarted the computer. I updated Malwarebytes' Anti-Malware (which I already had on my computer but the AV.exe virus wouldn't let me open anything). Then ran a full scan & it detected 2 Rogue.Installer on my system. (BTW, it didn't show up on my computer as av.exe, it showed up as setup.exe). I removed them & my computer is running fine now.

post for a visual on the malware part.
Hope this helps someone else. It was a pain!
