    The history of computer viruses has begun recently, but it has already become legendary. Almost everyone knows a few fables about these creatures, but hardly anyone understands what a computer virus is.
    A 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 a 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 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.
    Viruses are written by lone wolves or programmers groups.
    Using special programs called "Virus creators" even beginners in a computer world can build their own viruses. The aim of creation of viruses in such a 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.
    A computer virus group is an informal non-profit organization, uniting programmers-authors of viruses regardless of their qualifications. Everyone can become a member of the club, if he creates viruses, studies them for the reason of creation and spreading. You don't have to know any computer language or write any program code to become a member or a friend of the group. Programming in Assembler is preferred, Pascal, С++ and other high-level languages are considered to be humiliating. There are computer virus groups all over the world, few being more successful than others. It may be pretty hard to get in contact with them since they are quite typical representatives of a computer underground world as well as (free) wares groups. Sometimes, however, creating viruses can become a respectable occupation, bringing constant income. After all, no one but the author of the virus can bring valuable information on the way it should be treated and cured.
    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 dashes to buy an antiviral protection against even a most harmless virus. The ordinal behavior 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.
