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) before understanding what a computer virus is. A virus is a small organism that is only able to reproduce itself within another living cell or body. Many illnesses and diseases are caused by it and it is characteristically damaging to the cell or body that it inhabits.

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. Whereas the human virus damages living cells, the computers files and hard disc can be harmed by the computer virus. The computer virus can be concealed in a program, file or document and could be anywhere on your laptop.
Criminals, and other talented idiots with nothing better to do with their time, create these viruses and spread them to other people’s computers. This activity’s sole purpose is to create trouble and damage for every pc user. Other computers, files or documents can be ‘infected’ by the computer virus, similar to a common virus like the flu (which spreads from one person to another). Files and documents; such as word-processing documents, spreadsheets, emails, computer programs etc can have a computer virus spread through them. It can spread itself 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.
What does a computer virus do precisely? In fact, a ‘digital virus’ will make your computer ill, some can be very harmful, while others are created to simply annoy and just what each type will do to your computer depends on what it has been programmed to do. Some words used to identify various viruses are Macro Viruses, Email Viruses and Trojan Horses. You will be able to control the security of your computer when you understand the fundamentals about computer viruses.
