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.
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 alert 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,' eventhough sent 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.
