I am trying to clear a client's computer of a virus storm. When he called his Windows XP was restarting continuously. I was able to bring up the desktop restoring from a previous registry, however when I tried to initialize a Norton Anti-virus scan it crashed. When XP reboots there is a brief flash of a blue screen with some looking like, maybe, a command file. I am able to reboot in Safe mode. From there I have updated the virus difinitions and run several scans. The computer was evidently infected with ex.exe. I removed all files and edited the registry to eliminate ex.exe commands. These were identified as something risk.downldr. I checked, also, for the close.exe file. Also reviewed (and deleted) and file called "cmd.exe" in the root directory. Somewhere along the line a separate administrators account was established using Administrator, client's name.000. Hope this is detailed enough - I am really stumped.
