In this growing technological world, there is a dependency on computer systems. With the wide spread use of computer systems comes the threat of short programs that damage the system and other programs on that system. These short programs are called computer viruses. There are many computer viruses out there to infect unsuspecting system and programs. Along with these threats of infection comes the opportunity to eradicate these viruses before they infect systems. There are programs called anti-virus protection to help find and fix problems before they damage computer systems (

Computer Virus and Components

A computer virus can be defined as a rogue computer program, usually short in nature, designed to spread copies of itself to other computers and disrupt the computers’ normal operation. These viruses usually attach or insert themselves in or to a program or boot sector of a disk. It is spread through floppy disk, network, or routine on-line services. There are some viruses that are harmless, but others can destroy or corrupt data and cause an operating system or application program to malfunction. The three most common types of destructive computer programs are the Trojan horse, logic bombs, and the worm. “A virus is considered to be a worm with a logic bomb or Trojan horse component” (PC Upgrade).

Worms are programs that copy themselves. They create images of themselves in a file or a certain part of a disk. The main reason for including a worm component in a virus is to spread the virus via floppy dick. Now everytime you format a disk or copy a disc, the worm now infects you floppy disk. The Trojan horse is a program hidden inside another useful looking program. When the useful program is running the Trojan horse is doing something like erasing your Fat and directory. The last of this triangle is the bomb. The bomb is a piece of code embedded in a program or the operating system that waits for a particular event to occur.

In this essay, the author

  • Explains that with the wide spread use of computer systems comes the threat of short programs that damage the system and other programs on that system.
  • Explains that viruses attach themselves to other programs and are called parasitic viruses.
  • Explains that a trojan horse is hidden in an application program or injected into the program file or the boot record by the worm portion.
  • Explains that the jerusalem virus, cascade, brain, italian, and new zealand viruses account for most of the virus incidents in 1989.
  • Explains that the brain virus is a boot record virus that only has problem in the chaos strain.
  • Explains that macro viruses are the most widely spread viruses in the wild. they are designed to infect microsoft word and excel.
  • Advises that preventive medicine is the best way in preserving your system and preventing it from getting viruses.
  • Explains that anti-virus software protects files and disk drives from viruses. it uses binary codes and heuristics to detect suspicious codes or unanticipated changes.
  • Explains that the most popular anti-virus software is mcaffe and norton. both have excellent records when detecting and fixing viruses.
