I worked on a friend’s PC last night. It had a nasty virus that wouldn’t delete, no matter what happened —
Usually, deleting these nasty trojans with tools such as GiPo@MoveOnBoot or KillBox is a cinch.

Nothing worked, except for ComboFix. A description from the bleepingcomputer.com forums:
Combofix is a general tool that helps the helper cleaning up a Hijackthis log. It is able to remove some common infections and helps a user detect files that general scanners cannot find. It also lists registry keys such as the key keys, the desktop keys, and other areas where malware hide. The tool has some rootkit detectors too, allowing a helper to see if a rootkit is present on the PC.
When ComboFix runs, it shuts down explorer.exe, so don’t freak out when your desktop disappears and just let it do it’s thing.

Be sure to add ComboFix to your jump drive toolkit and use it next time you run into an undeletable virus. Let us know how it works out and if you know of any other useful tools like ComboFix, leave the tips in the comments.

Strange that would have showed up as a virus SpideRaY. Also, at the time I posted this I didn’t know that it expires after some time and you have to download a new executable (for security reasons). Thanks for the heads up. I have edited and fixed the post.
