Low-cost strategy developed for curbing computer worms

Researchers at University of California, Davis have developed a 2-pronged approach to ward off self-propagating infectious programs known as worms. The strategy enables computers to share information about anomalous activity and use an algorithm to weigh the cost of infection against the benefit of staying online.
