I decided to read up on viruses primarily worms because we had a worm in our groupwise system last year at school and it wasn't fun. We were all getting emails from each other that we hadn't sent each other, this is how the worm was spreading itself. The worm that I read about was the Mydoom worm. The worm was one of the worst experts say. It hit between 200,000-300,000 computers before it was stopped. It caused computers to slow down and meaningless messages to everyone infected. The subject line had technical terms in it tempting everyone to open it and read it. Many companies shut down their system until the worm was removed for good.
