When in doubt as to whether a virus is a hoax or not, check with the Computer Incident Advisory Center (
http://www.ciac.org/ciac/ ). They're the "police force" of the Internet, checking on viruses, hoaxes, chain letters, and other Internet incidents of a nefarious nature. They generally have the latest "scuttlebutt" on hoaxes circulating the 'net.
