MyDoom spawns four small offshoots
Security experts warned on Friday that several new versions of MyDoom have surfaced on the Internet, suggesting that worm writers are taking a stab at improving the venerable virus.
The viruses are largely alike: They are designed to spread by attaching copies of the program to e-mail messages and download additional features from compromised Web sites. Moreover, they are all difficult to clean from an infected Microsoft Windows-based PC, because they stop the system from connecting to antivirus Web sites to download updates.
The fact that several similar variations of MyDoom have been released in quick succession suggest that a more lethal version may be in the works, said Sam Curry, vice president of product management for Computer Associates International's eTrust software.
