Jeg vil ikke sige at han er dum, han glemte bare et par linjer kode... :-)
\"By definition, viruses do not have to do something bad. An early (and current) virus researcher, Fred Cohen, has argued that good computer viruses are a serious possibility. In fact, he has offered a reward of $1,000 for the first clearly useful virus; but, he hasn\'t paid yet.\" -
http://www.cknow.com/vtutor/vtgood.htm\"In the early 1980\'s, John Shock and Jon Hepps of Xerox\'s Palo Alto Research Center began experimenting with worm programs. (This was the first time that the term worm was actually applied to this sort of code.) The developed 5 worms, each of which were designed to preform helpful tasks around the network. Some worms were quite simple, such as the town crier worm, which simply traveled throughout the network posting announcements. Other worms were quite clever and complex, such as the \"vampire\" worm. This worm was idle during the day, but at night, it would take advantage of the largely idle computers and apply them to complex tasks which needed the extra processing power. At dawn, it would save the work it had done so far, and then become idle, waiting for the next evening.
However, although these programs were inherently useful, it became apparent that worm could be dangerous tools if incorrectly used. This was demonstrated amply when one of Xerox\'s worms malfunctioned during the night. When people arrived at work the next day, they found that computers throughout the research center had crashed. Moreover, when they tried to restart the machines, the malfunctioning worm immediately crashed them again. A \"vaccine\" had to be written to prevent the worm from crashing the systems.\" -
