Every time I get an email like the one below, I check it out on Snopes or Urban Legends, and usually they are not true, just a stupid form of chain letter spam. This one I am sorry to say is real.
"Subject: virus warning, please tell your friends
This one checks out and is a bona fide real virus so hence the warning.
Any email with "Mail Server Report" in the subject line is a new virus and should not be opened. It comes with an attachment in zip format. Apparently there is a Zip file attached so be very weary of any thing with a zip file on it.
The message tells you that a worm was detected in an e-mail that you sent out and asks you to open and install the attachment to fix the problem. Only, it IS the problem! DO NOT DO IT! Delete the e-mail.
This is a real threat.
You can check it out at Snopes:
You can Check it out for yourself at the Snopes address or Urban Legends at http://urbanlegends.about.com/od/virushoaxes1/a/mail_server.htm.
Never ever open an attachment from a source not know to you. You can forward suspicious emails with attachments to VirusTotal (email@example.com) to get a fre report confirming whether the attachment is safe or not.
