THIS IS AN EXTRACT IF AN EMAIL WARNING:

Hi All, I checked with Norton Anti-Virus, and they are gearing up for this virus!

I checked Snopes (URL above:), and it is for real!!

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 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 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.

COPY THIS E-MAIL, AND SEND IT TO YOUR FRIENDS. REMEMBER: IF YOU SEND IT

TO THEM, YOU WILL BENEFIT ALL OF US

Anyone confirm this as a Real concern??
