Get this E-mail message sent around to your contacts ASAP.

PLEASE FORWARD THIS WARNING AMONG FRIENDS, FAMILY AND CONTACTS!

You should be alert during the next few days. Do not open any message
with an attachment entitled 'POSTCARD,' regardless of who sent it to you.
It is a virus which opens A POSTCARD IMAGE, which 'burns' the whole hard
disc C of your computer. This virus will be received from someone who has
your e-mail address in his/her contact list. This is the reason why you
need to send this e-mail to all your contacts It is better to receive this
message 25 times than to receive the virus and open it.

If you receive a mail called' POSTCARD,' even though sent to you by a
friend, do not open it! Shut down your computer immediately.

This is the worst virus announced by CNN. It has been classified by
Microsoft as the most destructive virus ever. This virus was discovered by
McAfee yesterday , and there is no repair yet for this kind of virus. This
virus simply destroys the Zero Sector of the Hard Disc, where the vital
information is kept.
