Is your PC bot-infested? here's how to tell

As fireworks boomed on the Fourth of July, thousands of compromised computers attacked U.S. government Web sites. A botnet of more than 200,000 computers, infected with a strain of 2004's MyDoom virus, attempted to deny legitimate access to sites such as those of the Federal Trade Commission and the White House.
