What is a computer virus?

It is an executable code able to reproduce itself. Viruses are an area of pure programming, and, unlike other computer programs, carry intellectual functions on protection from being found and destroyed. They have to fight for survival in complex conditions of conflicting computer systems. That's why they evolve as if they were alive.

Yes, viruses seem to be the only alive organisms in the computer environment, and yet another their main goal is survival. That is why they may have complex crypting/decrypting engines, which is indeed a sort of a standard for computer viruses nowadays, in order to carry out processes of duplicating, adaptation and disguise

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Synopsis

The history of computer viruses has begun recently, but it has already become legendary. Almost everyone knows a few awesome fables about these creatures, but hardly anyone understands what computer virus is.

Computer virus is an executable code able to reproduce itself. Viruses are an area of pure programming, and, unlike other computer programs, carry intellectual functions on protection from being found and destroyed. They have to fight for survival in complex conditions of conflicting computer systems.

Viruses seem to be the only alive organisms in the computer environment, and yet another main goal is survival. That is why they may have complex crypting /decrypting engines, which is indeed a sort of a standard for computer viruses nowadays, in order to carry out processes of duplicating, adaptation and disguise

Viruses are written by lone wolves or programmers groups.

Using special programs called "Virus creators" even beginners in computer world can build their own viruses. The aim of creation of viruses in such way is pretty obvious: the author wants to become well known all over the world and to show his powers.

The results of the attempt can be very sad, only real professionals can go famous and stay uncaught. To write something really new and remarkable programmer should have some extra knowledge and skills.

After all, no one but the author of the virus can bring valuable information on the way it should be treated and cured.

 

 

 

 

Conclusion

Developers of antiviral software gain money from selling their remedy to a new widely hyped by the mass media virus. Agitation can grow so strong that all and everyone dash to buy an antiviral protection against even a most harmless virus. The ordinal behaviour of share indexes in stock exchanges while a computer virus epidemic is to fall. Somehow, the shares of high-tech companies producing antiviral software will soar up to the sky.
