Computer viruses.

Computer virus it's a special written program capable of spontaneous integrating into other programs, of creating new files and their copies with their further integrating into system spheres of computer for the purpose of programs operation irregularity, files and catalogues damaging and accumulating of various errors of computer's operation. Nowadays for about 6000 of viruses' types are known and with the laps of time this number increases.

There're three main types of viruses: boot viruses, file infectors and boot-file viruses. The most dangerous type is polymorphic viruses, they are the most difficult to detect and as a result to dispose. There're a number of ways for virus to get into computer, they are CD, disk storage units, computer nets and off course internet. If there's a problem there should be a way to deal with it, programmers creates antivirus programs to secure your computer and to help you detect virus or even prevent its penetration to your PC. Anyway according to specialists' opinion in case of viruses' penetration to your computer it's better to ask for help of the antivirus professional. Therefore some features of viruses confuse even rather skilful programmers, recently it was an unbelievable fact that virus is able to go through cold boot or spreads by the means of documents' files. Still, there's no chance for virus to cause greater damage for computer than fright to death user who don't know what to do with it. Every computer user has to learn at least a tiny piece of information about viruses and ways of their detecting and disposing.

Sometimes viruses are not as harmful as they considered to be, as the idea of creating viruses caused by the desire of several programmers to sold programs they create. As the matter of fact usually the birth of virus goes after standard scheme: one can't create a useful program that is easy to sell, in that case he creates virus program that will slowly 'eat' some files of your PC, usually they are files of the frequently use software, in order you notice it at once. Here we are, you know that there's something wrong with your PC and somehow you realise that the root of all evil is virus, so you search through internet for the ways to deal with this problem. And guess what, the same programmer who created the virus have already created the program to dispose it, and sure he would be glad to help you and to provide you with that panacea. Sure he wills, he was generous to grant you with virus and he will be just as generous to provide you with panacea, the only difference between two 'generosity' manifestations is that the second one demands some sum of money. You pay – he grants you with antivirus program and you computer is okay again. As a result the wolves are sated and the sheep intact.
