Don't usually do this but since I have been sent this virus 8 times today I thought I would let you know: 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.
