Computer virus is a program or codes that loaded onto your computer without your knowledge and run against your wishes and can copy itself. In thes research I will talk about computer virus and the differents types of computer virus and how it infects the computer.

Computer Virus

Is an external program for the purpose of making deliberately change the properties of the files they infect to implement some commands either removal or modification or vandalism and other similar operations.

In other words, computer viruses are programs that are written for the purpose of harming a compatible another, or to control and are written in a certain way so many styles and develop highly.(Fenlon, M, 2013)

Computer Virus characterized as:

1- A Program copy and replace itself.

2- The computer virus connects itself to another program called an incubator.

3- Computer virus cannot establish host by itself .

4- Computer virus can move from an infected computer to another undamaged.

The Computer Virus consists of four main parts:

1- The Replication Mechanism: it is the part that allows the computer virus to copy itself.

2- The Protection Mechanism: this part hides the computer virus from detection.

3- The trigger Mechanism: Allow the virus to spread before the user knows his presence.

4- The Payload Mechanism: The part that performs computer virus.

Files types that the virus can infect:

In general the virus infects executable files or encrypted files is a text such as the following:
