What is it?

A variant of W32/Sober.gen@MM, W32/Sober@MM!M681 is another
mass-mailing worm hiding inside a spam email attachment.
When run, the virus displays a fake error message, infects
the host computer then sends itself to stolen email
addresses. Note: VirusScan users with the latest DAT file
are protected from this threat.

What should I look for?

FROM: Varies
SUBJECT: Examples: Registration Confirmation; Paris Hilton &
Nicole Richie; hi, ive a new mail address
BODY: Example: hey its me, my old address dont work at time.
i dont know why?! in the last days ive got some mails.
i' think thaz your mails but im not sure!

How do I know if I've been infected?

Fake error message ('Error in packed Header') displayed.
Outgoing messages as noted above. Note: Receiving an email
alert stating that the virus came from your email address is
not necessarily an indication you are infected. Mass-mailing
viruses often forge (or 'spoof') the from address.

What can I do?

Besides keeping your anti-virus protection current,
fortify your PC security by installing McAfee Personal
Firewall Plus -- recommended against threats like
W32/Sober@MM!M681 that need Internet access to spread.
