“A fast-moving e-mail virus that appears in in-boxes as a transmission error continues to spread across the Internet.

The virus, which has been called MyDoom or Novarg, shows up in e-mail in-boxes under a variety of subject lines, including ‘Error,’ ‘Mail Delivery System,’ ‘Test’ or ‘Mail Transaction Failed’….

Once the virus infects a Windows-operated PC, it installs a program that allows the computer to be controlled remotely. According to Network Associates, infected PCs will be used to launch a denial of service attack against the Web site of SCO Group starting Feb. 1.

According to antivirus software maker Symantec Corp., Cupertino, Calif., the virus is programmed to stop spreading on February 12.”
