I've got the WinFixer pop-up virus. Seems to avoid attempts to eradicate by any means. Tried Spybot, Ad Aware SE, Pocket Killbox, Hijack This, Ewido, Cleanup, and Spyware Blaster w/o suck-sess. I'm once more going through ditto's "required steps" but Ad-aware SE is freezing up on me, so I don't know how effective that will be. We'll see.
I'll see if I can't pin this down any better before I post more details, but if someone has any sage advice I'd appreciate it.
Oh, and if you run into anyone responsible for WinFixer on the street, punch 'em in the neck for me. Much abliged.
