virus!

You  should be alert during the next few days. Do not  open any
 message with an attachment entitled  POSTCARD FROM HALLMARK, 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.
 
 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.
