Norton and Mcafee both have excellent sites that aid you in manual removal of virii. My suggestion is to take a little bit of time and LEARN about your virus. Read up on and it figure out EXACTLY what it is doing to your system. Only once you understand your virus will you be able to feel safe about your system once you've cleaned it.

Also *note*: If the virus is bad enough to cause a complete system re-load and you do the f-disk thing. Do this command as well-->

fdisk /mbr

/*This command fdisks your Master Boot Record*/ It's a nasty place a virus can hang out and resurface after a perfectly good fdisk/format/clean install.
