Computer Viruses Computer Viruses In recent years, the explosion in the use of networks and the Internet has created a new avenue for computer viruses to spread at a rapid rate. Earlier viruses used executable files and would typically be no more than an annoyance by displaying harmless phrases. The latest viruses are much more sophisticated and able to cause extensive and irreparable damage to files. Some viruses are able to spread themselves to other computers on the Internet or network causing widespread damage to many systems. What is a computer virus' A virus is a piece of software designed and written to adversely affect your computer by altering the way it works without your knowledge or permission. In more technical terms, a virus is a segment of program code that attaches itself to one of your executable files and spreads systematically from one file to another. Computer viruses do not spontaneously generate. They must be written and have a specific purpose. A computer virus (virus) is a program that invades computer systems and performs a variety of damaging tasks after a "trigger" event occurs. The "trigger" event can be as simple as starting up a word processing program or opening virus, computer, viruses, program, files, system, software, infected, anti-virus, damage, programs, one, scanner, e-mail, might, itself, file, disk, systems, new, attachment, another, able, trigger, spread, sender, recent, open, must, message, malignant, internet, event, benign, work, without, spreads, should, sector, run, remove, protect, next, known, know, executable, designed, created, check, cause
