Well, Here is a place that will help you get rid of this current problem: http://www.help2go.com/Tutorials/Spyware_I...SpyJack-F).html
If you keep going from one problem to another problem one right after another like this is the second one and there might be more to follow, personally I think your system is over infected. One suggestion is to quit using these trial versions of everything (They go out of date and do not work properly) and get rid of the stuff from Symantec (Norton) It leaves a lot to be desired unless you like paying for being infected.
If you still have problems with virus, worms, trojans and spyware after running the fix above I would suggest (I know I am going to get in trouble here for this) backup all of your data and then reformat and reinstall Windows and start from scratch. I would then suggest installing Service Pack 2 and a good free firewall, and good anti-spyware programs. believe me you do not have to spend money to be covered. I do not and I am covered very nicely.
