There are all kinds of hoaxes on the Internet and not surprisingly some of them deal with security issues. If you are concerned about suspicious or unusual advice you got from someone and you can't find any information on that issue, it might indeed be a security hoax. If this seems to be the situation, we recommend that you visit The Symantec Security Response Hoax Page to learn if your suspicions are real. Another great resource is The Computer Incident Advisory Capability (CIAC) Hoaxbusters web site that is sponsored by the US Department of Energy and maintained by the Lawrence Livermore National Laboratory. This web site includes lists and information on all kinds of Internet hoaxes, legends, chain letters and scams.
