A new digital plague has hit the Internet, known as Conficker or Downadup, infecting millions of personal and business Windows-based computers in what seems to be the first step of an unknown multistage attack.

Experts say it is the worst infection since the Slammer worm exploded through the Internet in January 2003, and it may have infected as many as nine million personal computers around the world.
