I got the following from a strange source. So take it with a pinch of sort, at a risk. Mind you I use Ubuntu so I'm not effected. Just for you Windows users, I would think.
ALERT: WORST VIRUS EVER - Worldwide News
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. This virus simply destroys Sector Zero from the hard disk, where vital information for its functioning is stored.
This virus acts in the following manner:
It sends itself automatically to all contacts on your list with the title:
â€œA Card for Youâ€.
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 donâ€™t open any mails with the subject: â€œA Virtual Card for Youâ€. As soon as you get the mail, delete it!! Even if you know the sender!!!
