My computer got some kind of trojan virus and when I press ctrl+alt+del to go to the task manager...it's gray meaning I can't click on it. Also my system restore doesn't work. It says that it has been removed from my OS. I have Windows Xp Professional, I know the best thing to do would be to wipe my hard drive and reinstall windows...but I don't have the cds. Any suggestions as how to get these functions working again would be awesome. Thanks.
