Internet Exlporer Not Responding

HELP! I have been having problems with my internet explorer and outlook. I cannot get IE6 or outlook to open. At first glance, I thought that I had the problem with the latest Microsoft updates, however, the other profiles on my computer (HP) are not having this issue. They can access IE and outlook. I have gone through the steps and removed the latest updates from Microsoft, then I reinstalled them and went through the "fix" procedure that MS has posted on its website. Still nothing. I was able to get my profile to work for a few hours and then it quit again. MS issued another "fix" on 4/25 and I downloaded it and this still did not resolve my problem. I have reinstalled/repaired several of the *.dll files, and still nothing. I am thinking that I may have some kind of spyware on my computer, but I do not know what it is. I have ran Spybot, Ad-aware, ewido (web scan), and my anti-virus and nothing seems to be helping. Any help is GREATLY appreciated!

Thanks….I have tried that already too. Still nothing. I cannot get the control pannel to open. When I go to log off, the end program window comes up and shows that it is shutting down a program. Right before XP shuts down, the control panel will open and then the computer restarts or logs off…depending. Any other suggestions are welcome!!!
