Complete 6 pages APA formatted article: Basic Concepts of the Computer Virus. A computer virus is a small software program that is developed and spread from one computer to another to interfere with computer operations. Additionally, a virus can delete or corrupt data on our computer, make use of our e-mail program to extend its circle to other linked computers, or even delete our particular data or everything from our hard disk (Microsoft Corporation, 2010). However, computer viruses can be found and developed in any part of the world. In addition, they are created to work on our computers, without our authorization, as well as in many instances, destroy the data and information on our computer. Additionally, several viruses are not dangerous for computers however they irritate us by giving warning and displaying messages. In addition, various viruses harm data in a computer, on the other hand, other viruses, once they enter into a computer, will obliterate the data stored in the computer (Ray, 2004, p.137. Shelly et al., 2005. Norton, 2001). These dirty programs are written by some "dishonest" people. These virus applications are put into the commonly used programs or applications so that when that program will run the linked virus program will also be executed. In this way, the virus "infects" the executable file or program. Furthermore, viruses operate in a similar way as DOS or Windows machines and can infect zip or exe files (Myron, n.d).

It is essential to know how the virus spreads so that we can take some effective actions to prevent the virus from spreading into other computers. A virus can enter into our computer via web sites, email, diskettes, or other media. Thus, it is essential to be very cautious regarding what we permit within a computer and networks. Also, to make secure a computer from virus attacks, we should install antivirus software and we should scan each application before running (Ray, 2004, p.137) and (Myron, n.d).

In addition, viruses also spread via some greeting cards, funny images, or audio as well as video files.&nbsp.
