I just got done cleaning a machine with blaster on it yesterday.

Download and run FixBlast by Symantec -

Then go here and read up on what you're experiencing -
http://www.microsoft.com/technet/tre...n/MS03-026.asp

Towards the bottom of that site, you'll find the download links.

After that, run Windows Update and patch yourself all up, and get yourself a free personal firewall. - www.agnitum.com/download/ or www.tinysoftware.com
