You all prolly know this already but..
W32.Novarg.A@mm is a mass-mailing worm that arrives as an attachment with the file extension .bat, .cmd, .exe, .pif, .scr, or .zip. When a computer is infected, the worm will set up a backdoor into the system by opening TCP ports 3127 thru 3198. This can potentially allow an attacker to connect to the computer and use it as a proxy to gain access to its network resources. In addition, the backdoor has the ability to download and execute arbitrary files.
The worm will perform a DoS starting on February 1, 2004. It also has a trigger date to stop spreading on February 12, 2004.
