Postcard Computer Virus

This was around before but has resurfaced again this time most often saying you have received a postcard from Hallmark. DO NOT OPEN ANYTHING THAT SAYS YOU HAVE RECEIVED A POST CARD FROM ANYBODY!! It is a really bad computer virus! DELETE IT IMMEDIATELY!!
Here is the link to snopes so you can read about it yourself so you can see what form it might come in.

I have actually been getting the Hallmark one lately and knew better than to open it. Thanks Carol (W.O.W) for reminding us all about it again.

This just in from a reader: There is another that surfaced a few weeks ago in my company. It says it's from Delta Airlines thanking you for your purchase of tickets and that the full amount has been charged to your credit card. It says you can review the invoice which is included as an attachment. If you open the attachment, it unleashes a terrible trojan that you cannot get rid of without reformatting your hard drive.

Update: Another virus which appears to be an email coming for UPS or Fed Ex
