PLEASE SEND THIS TO EVERYONE ON YOUR CONTACT LIST!! On your e-mail adress!

A new virus has just been discovered that has been classified by
Microsoft as the most destructive ever. This virus was discovered
yesterday afternoon by McAfee . This virus simply destroys Sector Zero
from the hard disk, where vital information for its functioning are stored.

This virus acts in the following manner:
It sends itself automatically to all contacts on your list with the title:

'You've received a Post Card from a Family member'.

As soon as the supposed virtual card is opened the computer freezes
so that the user has to reboot. When the ctrl+alt+del keys or the reset
button are pressed, the virus destroys Sector Zero, thus permanently
destroying the hard disk. Yesterday in just a few hours this virus
caused panic in New York , according to news broadcast by CNN.

So don't open any mails with subject:'A Post Card from .' As soon
as you get the mail, delete it !! Even if you know the sender !!!

Please pass this mail to all of your friends.
