Let me refer you to the Symantec Virus Hoax page :
http://www.symantec.com/avcenter/hoax.html
Most of these hysterical warnings - they are in ALL CAPS, they warn of dire consequences (your hard drive will be inserted in parts of your body not intended for electronic components!!!!), and they ask you to "send this warning to EVERYONE YOU KNOW!" - are just baloney. They come from frustrated individuals with an insufficient work load, who need to receive a swift kick, and then be handed a broom and told to get to work.
Don't pass this stuff on, and if you get one you haven't seen before, check out the hoax pages - you'll probably find it there.
