Computer Viruses Hit Milestone; Cure Remains Elusive

The original computer worm that surfaced in 1979 was designed to scour a network for idle processors to enable more efficient computer use. Stuxnet, a worm discovered in July 2010, infects, spies on and modifies the control systems of industrial utilities, including nuclear systems. It is the most important malware yet seen, says Hypponen.
