Definition of Computer Virus


Computer virus may be defined as a small software programme which has the capability of reproducing itself which may result in significant harm to files and/or programmes on the same computer. It is said that true computer virus only spread to another computer with the aid of human assistance. This is so because human has to write the virus programme and set up the various ways in which the programme can be spread. There is no standard size of the virus file, but it may range between 1-300 Kb. These computer viruses may begin by having a negative effect on the programme causing it to run incorrectly or corrupt the memory of the computer. These two scenarios can eventually lead to crashing of the computer’s hard drive.

No one wants his/her computer to be infected with virus. Because of this some people will invest a lot of time researching the various types of computer virus and the security threat that is related to each type. This reach is done in order to find out the nature of the virus such as how the virus is programmed, ways in which the virus carry out the damage to the hard drive and very importantly the methods by which they are spread.

Virus will attack various sections computer system such as the boot sector, the browser, various files among other areas.

Examples of some computer viruses are:
  1. Actifed - this virus infects .COM and .EXE files.
  2. AGENA - this virus resides in the memory infecting .COM and .EXE files
  3. Ada - This virus can infect any of the DOS operating system


The often confusion between Micro-organisn Virus and Computer Virus

When you hear the word virus the first thing that comes to your mind is some agent that causes disease. This is true in that micro-organism virus is the cause of some deadly disease of human, animals and plants. Similarly computer virus is the cause of many hard drives and other removable drives to crash thereby rendering this equipment none functional or useless. But often times there are confusion between micro-organism virus and computer virus. Micro-organisn virus cannot cause computer virus.

As someone who is trained in Agriculture and some aspects of Computer Technology, I had been approached on several occasions by people asking me if computer virus can affect human, animals or plants and vice versa. I had been at pains to point out that there is no relationship between computer virus and micro-organism virus. In no way can computer virus affects human, animals and plants. Also, in no way can the micro-organism virus affects the computer hard drive or any removable device.

In order for you not to confuse the micro-organism virus with computer virus, you will have to look at their definition. Micro-organism virus is a living organism. Computer virus on the otherhand is a small software programme capable of reproducing itself which may result in significant harm to files and/or programmes on the same computer.

With the distinction between Micro-organism virus and computer virus, there is no way computer virus can affect human, animals or plants and vice versa. Computer virus may have been developed based on the function of micro-organism virus. So please disabuse your mind of the often confusion between micro-organism virus and computer virus.

Belly fat is like a friend who means you no good and the only thing left for you to do is to tell him/her goodbye.
