At every page that I go to on IE a error box pops up saying "There is a bug in your system do you want windows to debug?" It's a runtime error box. Anyone know what might be causing it? And also every time windows is started, We get this Prevx CSI program pop up saying that are computer is infected with a worm, even though Norton's 360, Spybot Search & Destroy and PC Check up doesn't pick it up. What can I do?

Hi, welcome to daniweb.
Use the removal programs noted HERE If the instructions say to have the program clean or Remove Selected then please do so.
Ignore the instructions for DSS Scanner and download instead HiJackThis and run a full system scan and save the log.
Post back here with the requested logs
