Join the Crew, Elfbowl, Lump of Coal and more are all examples of virus hoaxes. Please, please, please before forwarding another "This is a virus warning and it's for real cause my friend got it from a VERY reliable source..." email, check with the McAfee List of Virus Hoaxes. There has never been a case of an authentic virus being reported via email. Chances are any warnings you received that don't point directly to a reputable web page detailing the virus and solutions are a fake.
