About the Virus Information Library More than 57,000 virus threats exist today. The McAfee AVERT Virus Information Library has detailed information on where viruses come from, how they infect your system, and how to remove them. In addition to genuine viruses, the Virus Information Library contains useful information on virus hoaxes, those dire email warnings about disk-eating attachments that sometimes land in your inbox. WOBBLER and Good Times are two of the best-known hoaxes, but there are many others. Next time you receive a well-meaning virus warning (unless it's from us, of course!), check our hoax page before you pass the message on to all your friends.
