COMPUTER VIRUSES.

Computer viruses as we know then are micro organisms causing various diseases in human body, Computer too does have viruses. However, computer viruses are just a generic termed used to described a group of willfully written destructive computer program. Computer viruses are to computer while micro organism are to human body. Computer viruses are pieces of computer codes rather than living micro organisms. But they share several attributes of biological viruses, hence they have been referred as computer viruses.
TYPES OF COMPUTER VIRUSES;

Computer viruses cause damages (in some cases, death) to the system. They infect the sensitive organs of the system thereby reducing the performance and the working capacity of the system. They also induce poor working ability to the entire system. There are several types of known computer viruses militating the performance of computer. some of the known viruses include the following.

Stone viruses
yankidoodo viruses
Jerusalem viruses
Tuesday viruses
Norm viruses.
Trojan horse
Bomb
The list is endless.

EFFECTS OF 3 MAJOR VIRUSES.

The most dangerous viruses are Trojan horse, Worm and Bomb.

A Trojan horse viruses behaves like the Trojan horse of Greek mythology. A malevolent program is hidden inside of a useful program. While the useful program is running, the destructive potency of the Trojan horse becomes alive and erase some of your computer's important files stored.
A computer norm virus replicates itself. It create its own image either in a file or a particular section in the disk (hard) and from that position contaminate the entire system.
A computer Bomb viruses is a piece of code tactical embedded in a program or at the operating system itself that waits for an opportunity. When the opportunity occurs, the logic bomb goes off which now result to some kind of damage to the computer.

CLASSIFICATION OF COMPUTER VIRUSES.

Viruses can be classified by their habitat. Some viruses inhabit in other program. These are known as parasitic viruses. Other types of viruses choose the boot sector of the floppy or hard disk and is classified as boot sector viruses.

Parasitic viruses begin when the executable file to which they are present is running. The boot sector viruses enjoy the hard drives section. Once the computer reads the sector, the viruses becomes destructively active. Viruses are destructive software that spread from one program to another or from disk to disk. Computer viruses, like biological viruses, need a host (victim) is an innocent program. If a computer program is transferred to another system, the programs in the entire system will be ruined automatically.
SOLUTION TO COMPUTER VIRUSES.

There are always solutions to every problems, however there are several methods that can be used to detect or destroy viruses. Each method has its potency and weakness. It is important to know exactly how much protection your anti-Virus software can offer you. It would be nice if anti-virus really stopped viruses from spreading and attacking your computer. The following anti-virus software can be used to control or stopped some computer viruses.

Norton ant-viruses from semantic corporation.
Mc Afee.
Dr. Solomon's anti-viruses.
Avast anti-virus.
