Sample of hoax message:

Dear All,
For your reference, take necessary precautions.  If you receive an email with a file called California, do not open the file.  The file contains WOBBLER virus.

WARNING
This information was announced yesterday morning from IBM; AOL states that this is a very dangerous virus, much worse than "Melissa", and that there is NO remedy for it at this time.  Some very sick individual has succeeded in using the reformat function from Norton Utilities causing it to completely erase all ocuments
on the hard drive.  It has been designed to work with Netscape Navigator and Microsoft Internet Explorer.  It destroys Macintosh and IBM compatible computers.  This is a new, very malicious virus and not many people know about it.
