Virus again

It is necessary to distinguish two basic actions (phases) which are carried out by a computer virus: reproduction and display. Reproduction usually is the first and obligatory action of a virus at reception of management. The display phase on which unapproved actions are carried out, can alternate with reproduction, begin through the certain (incubatory) period or at a combination of some conditions. It can consist in refined visual or sound effects, it can include or consist of drawing of damages to file system. Damages can be massed when, for example, FAT and other system blocks is erased, or on the contrary, distributed when small, difficultly found out damages are often enough carried out. At a number of viruses the display phase is absent, i.e. besides reproduction they do not carry out any unapproved actions. At the same time any virus possesses a number of by-effects which have not been provided at virus creation but which actually concern its displays. The most frequent by-effect is lag of an operating system or loss of working capacity of some (more often resident) programs. Other important by-effect is occurrence of some “inexplicable” messages of an operating system.

Along with the specified actions, the virus can possess a certain latent phase during which any actions on the reproduction or display are undertaken. The latent phase can be caused by the certain time of period (for example, certain month or year), a configuration (for example, the virus can become more active only at hit on the winchester) or hardware features.

The length of a way from originally infected program to the program in which this virus has been found out for the first time, can be enough big. Practice shows that usually as the primary carrier of a virus the popular game program or the new version of popular software product acts.
