What is your installed antivirus software?

You may wish to download (on an uninfected PC) one or more of the following rescue scanners to create bootable media to scan the infected PC (list courtesy of forum member, GreginMich):

Each rescue scanner will miss things – because none of them will have a perfectly complete and up-to-date set of definitions; so you might need to use several of these rescue scanners, or something like the Shardana Antivirus Rescue Disk Utility, which creates a custom bootable CD or flash drive that includes multiple rescue scanners:

Another boot CD (similar to Shardana) to consider is Hiren's Boot CD.
