have me and you discussed virus software before? That is EXACTLY the virus cocktail that I use!!! Unfortunately, my son downloaded so much crap in a span of a few days earlier this year that I lost my first virus battle since using this virus cocktail. I almost got it, but some Trojan buried itself deep into my registry and when I finally thought that I beat the viruses, the computer needed to reboot and when it did, it booted back up with the Blue Screen of Death and said that my kernel file was failing. DOH!!
The PC the kid is on has a lot of restrictions on it now, because she says 'OK' to anything that pops up on the screen. Now she has the UAC implemented and she can't download anything without express permission.
Did you try an older System Restore point?
