Quick virus removal

If you are pretty sure there's a virus on your system, and you haven't been running any antivirus software, there's a pretty good solution to at least get you partially repaired.

McAfee AVERT Stinger is a free, standalone program that can detect and remove about 45 of the most common viruses out there. It's nice and portable, so it's not a bad idea to keep it on your portable USB drive, just in case someone you know needs a quick scan/repair.
