6 3 What do viruses do?Ĭomputer viruses insert their own executable instructions into the normal code of their hosts. However, despite irrefutable proof of its origin, the story has never been retracted. This story has spread through various documents written in the years since then until many people seriously believe that it was a real event. Unfortunately, the report was based on an April Fool's joke published in 1991 that had caused computer-savvy readers to chuckle briefly and move on to the next spoof.

This report gained wide publicity through the work of a television news show. This virus was supposed to have been inserted in the printer ROMs of equipment sent to the Iraqis before the war the report said that the virus crawled up the parallel interface cable and infected the host computers running the printers. News and World Report in January 1992 published an article about the 'Iraqi Virus' that had supposedly been used by the US in the Gulf War against Iraq. In a splendid example of faulty fact-checking, an issue of U.S.

Several callers to the NCSA virus hotline asked whether viruses could enter their computer through the power cord. During the Michelangelo scare of 1992, parents were reported as having threatened to take their children out of school for fear the computer virus would affect their health. The popular press has confused the public about these distinctions and seems to apply the word 'virus' to practically any kind of computer problem, whether involving replicating code or not. They do not integrate their code into host programs. Worms are free-standing programs which replicate, usually in networks. Some macro viruses have been demonstrated to exchange executable code without human intervention when they infect the same documents. Computer viruses even show some parallels to sexual reproduction: they can exchange 'genetic' material through the agency of the twisted human beings who enjoy creating harmful programs and who share their knowledge with each other. When victims distribute infected programs, diskettes and documents, the viruses extend their range. They insert themselves into other host entities, thus spreading the infection. These parasitic programs commandeer CPU, memory and disk resources to replicate themselves. Once these infected programs are executed, the computer viruses, like biological viruses, subvert the normal functions of the operating system (OS). Viruses are little programs that copy themselves into 'host' programs, into documents or other files from Microsoft Office products, or into special executable 'bootstrap' areas of disks. With the help of unethical, immoral, careless, stupid or crazy virus authors, viruses evolve in response to selection pressures, hiding themselves in new niches of the computer universe, or 'cyberspace.' Virus authors even take ideas from each other's viruses, leading to a form of primitive viral sexuality. Aggressive anti-virus programs (AVPs) contend with viruses in memory and on disk. Some are mutating at a furious rate, spawning offspring in the blink of an eye. This isn't entirely science fiction any more.Ĭomputer organisms are reproducing worldwide. 5 At about the same time, researchers at Xerox Palo Alto Research Center (PARC) experimented with using 'worms' to perform basic maintenance functions on their local area network. John Brunner's classic book Shockwave Rider described a program called a 'tapeworm' that could roam the global network, cleaning up information per the sender's programming. 4 It was a common joke among science fiction fans that one day the North American telephone grid would develop consciousness. 3 Others imagined life-forms evolving in computer networks and predators seeking them out and destroying them. In the early 1970s, author David Gerrold named a program VIRUS and imagined it spreading from computer to computer through phone linkages.

Science fiction authors have long written about artificial life forms.
