myDoom/Novarg mass-mailing worm
MyDoom is a mass-mailing worm that masquerades as a test message. MyDoom (w32.mydoom@mm, also known as Novarg, Shimgapi, Shimg, and MiMail.r) takes advantage of the ZIP file format's ability to pass through e-mail filters. It also uses Kazaa to spread. Within the first few hours, MyDoom spread quickly around the world. It affects only Windows users, not those using Macintosh, Linux, or Unix. Much of the worm's code is itself encrypted, and antivirus firms are still studying it. It will self-terminate on February 12, 2004. Because MyDoom spreads via e-mail and could severely slow or shut down e-mail servers with excess traffic, this worm rates a 7 on the CNET Virus Meter.
One of the emails Swen uses to spread is a professional-looking message that appears to come from "MS Technical Assistance", and contains a notification of a "September 2003, Cumulative Patch", along with the virus attachment.
Removal:Almost all antivirus software companies have updated their signature files to include this worm. This will stop the infection upon contact and in some cases will remove an active infection from your system.
