An Introduction About Compiter virus

Before understanding what a computer virus is, it is necessary to understand what a virus is when it occurs in a living form (such as a human body, an animal, or a plant). A small organism, a virus is only able to reproduce itself within another living cell or body. It is the cause of many illnesses and diseases and is destructive to the cell or body in which it lives. No Adware spyware and adware cleaner scans, protects and removes spyware, adware, malware, trojans and thousand other bad objects.

The word virus comes from Latin and literally means ‘poison’ and that is basically what it is - a ‘poison’, able to reproduce itself within another cell or body and an example of an illness caused by a virus is the flu. Well basically, a computer virus is a harmful computer program which will damage files or your computer, and which is able to duplicate and spread itself within a computer or computer network. Usually hidden within a program, file or document, a computer virus can be anywhere on your processor.

There are some clever individuals who have nothing worthwhile to do with their time that create and spread these computer viruses. The sole reason for doing this is to cause havoc. Files and documents can be severely damaged when a computer virus enters the computer, similar to the effects of influenza upon the human body. Files and documents; such as word-processing documents, spreadsheets, emails, computer programs etc can have a computer virus spread through them. As well as through removable storage devices such as memory sticks and floppy disks, it can spread itself through the Internet and through local computer networks. As it is concealed and difficult to identify, it can be inadvertently passed on to other computer users.

A computer virus is comparable to a human virus in that it causes illness to its host. Some are very destructive while others cause minor irritations, making your computer seem ‘under the weather’. Examples of terms used to describe different types of computer viruses include Macro Viruses, Email Viruses and Trojan Horses. Understanding the basics of what viruses are is the first step to learning what to do about them, and how to be completely in control of your computer’s security.
