Go to start, run, type msconfig and then go to the general tab and look through the startup entries and see if you see one called ad-rotator or something similiar, uncheck it if you found it, disable all if you haven't, then reboot. Now run your spy-ware programs and see if that don't help. Is it in your add/remove section? Can you check to see if it's in your C:/program files and if so, delete it.
