Did you tried BitDefender Total Security 2008?

If Yes i think you may Reinstall Windows on your computer.

Do this. Download the program below and install it. Then run the START UP MANAGER and uncheck any box that looks suspicious. It could be launching that box at start up.
either your computer is f'd up or you have an illegal copy of windows.

Is it Vista? I thought they had some special registration thing you had to do...
