WORST EVER VIRUS (CNN announced)

PLEASE SEND THIS TO EVERYONE ON YOUR CONTACT LIST !!

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 and no vaccine has yet been developed. This virus simply destroys Sector Zero from the hard disk, where 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 "A Virtual Card for You." 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.

This alert was received by an employee of Microsoft itself. So don't open any mails with subject: "A Virtual Card for You." As soon as you get the mail, delete it. Please pass this mail to all of your friends.

Forward this to everyone in your address book.

I would rather receive this 25 times than not at all. Also: Intel announced that a new and very destructive virus was discovered recently.

If you receive an email called "An Internet Flower For You," do not open it. Delete it right away! This virus removes all dynamic link libraries (.dll files) from your computer. Your computer will not be able to boot up!!
