What to Do If Your Computer Has Been Infected

Aug. 17, 2005 — -- A software worm wreaked havoc for many Windows-based computer users and businesses on Tuesday, virtually crippling computer networks at media outlets such as ABC, CNN and The New York Times.

The malicious software code is believed to be a new worm called "Zotob." During the past week, Microsoft and computer security companies warned this new worm could allow an attacker to access PCs by exploiting a recently discovered flaw in Windows 2000.

Becky Worley, a tech expert and author of "Security Alert," joined "Good Morning America" with important information on the virus and what to do if your computer has been infected.
