I too am experiencing this problem and I found this forum via a Google search. I dl'ed and installed Hijackthis and ran it, the log to follow. The problem I've been intermittently experiencing is multi pronged, I have ad-aware from Lavasoft installed but I can't dl new definitions. I have Symantic AV and it's been catching new viruses lately. I can't do a windows update, it takes me to a Google page that says it can't find the requested page. Any help would be greatly appreciated, and I'll never dl from torrent sites again.
