A new destructive e-mail virus named “W32/Bugbear@MM“is spreading all
over the world. Simply opening or previewing an infected message in
outlook or any other e-mail reader can result in infection. It attempts
to send itself to email addresses found on an infected system. It also
spreads through open network shares and has the ability to send print
jobs to printers found on an infected network.

The message body and subject vary widely. The attachment name also
varies. It is common for the attachment name to contain a
double-extension (ie. .doc.pif), but this may not display on all
systems.

Please make sure to delete any suspicious e-mails before even previewing
them and make sure your anti-virus software is up-to-date

How can it execute itsefl if I just open message without executing any attachments? (and my e-mail client isn't outlook)

A new destructive e-mail virus named “W32/Bugbear@MM“is spreading all I have not seen it yet in our virus reports. More Klez than anything.

I don't know but any messeges have W32/Bugbear@MM don't open it and delete

Simple solution... Just don't open attachments (That is never, ever ever :D)

Only open one when you know someone is going to send you something, thats about it...

Norton flagged this one coming from one of my customers this morning. Update those defs!
