When you say it blocks the site do you mean nothing happens or that a message pops up?, because my software spots each attempt, but the message is as annoying as the ads. Anyway I just installed sp2 (yeah I know my fault for not doing it before) and I'll try spybot. I should point out some of the adds are just an ad in the middle of my screen and others opens a new browser window to their website. I think I'm actually getting somewhere though. If I fail I can at least tell my self I did everything I could.
Edit: I don't know is this is funny or not, but sp2 was blocking spybot from being downloaded
