if you deleted infected files that are also needed for running Windows, your computer will die like that. you need to boot from your Windows Setup CD and reinstall Windows, make sure that the antivirus program is loaded, then connect to the Internet to reinstall all Microsoft Windows updates. don't ever connect to the Internet directly without a firewall running. if you are using dialup to one of the major providers like AOL or MSN, the firewall issue is less important. any broadband connection requires a firewall.
the average time it takes an unprotected computer connected by broadband to the Internet to be infected by a virus is 2 seconds. this assumes you already have an antivirus program and all of Microsoft's critical updates installed.
