Somewhere I must have picked up a "bug" basically what its doing is just bringing up pop-ups. Usually the pop-ups are like online casinos or something about a subject I might be looking for like spyware. As im typing this its not really doing anything but if i switch to another website like espn or yahoo or just most other sites in general you can tell its doing what it does. The page will sit there and click about every 4 seconds like its refreshing or a pop-up is trying to come up. I have never seen or experienced something like this. My nortons ran out. I have used spysweeper and microsoft-antispyware and some others. Nortons and spy sweeper did detect something but wouldn't get rid of it. I tried to do it in safe mode but couldn't find it anywhere. AVG doesnt detect it and neither does Microsoft anti-spyware. What is a good program to use to get rid of this problem?

Thanks ahead of time.
