Wow, lots of traffic!!
Well... i used to run ad-aware (which removed a lot of spyware). Then I ran spybot (a few weeks ago) and it found a crap load (technical term) more including ad aware. I used noadware as posted before (thanx Seriak ) which removed more spyware which was part of my problem.
I re-ran spybot which told me that adware was spyware and illegally using spybots files!!
So... my computer is working fine now that I have change things as posted before.
If you haven't or don't check for spyware, my guess is that it is on your computer.
I think my prob was a combination of virus and spyware.
So I guess I can go back to the porn sites.
