Microsoft on Wednesday made available a free software tool to help victims of the worms that hit Windows computers in the past days clean their systems.

The Zotob worm started spreading on Sunday. Since then it along with many of its variants and other worms that take advantage of the same Windows security flaw have hit Windows 2000 users in particular. Systems at CNN, ABC and The New York Times were among those infected.

The cleaning program is an updated version of Microsoft's Windows Malicious Software Removal Tool, Debby Fry Wilson, a director in Microsoft's Security Response Center, said in an interview.

"You click on it and it will tell you if you are infected," she said. "And if you are, it will clean the worm off your PC.",39020330,39213717,00.htm
