Samething happening to me, those websites are popping up for no reason even if I'm not on my browser. Scanned with Ad-Aware, Spybot, Giant Antispyware. Nothing shows up in Hijackthis, only valid entries. Starting to get really annoying spent the whole day trying to figure out the problem. I'm not a novice at getting rid of spyware either but this particular one is just really hard get rid off, nothing seems to be working. I think this is a new spyware.... thats why the scanners aren't picking it up.
