Computer viruses

A virus is a piece of software designed and written adversely that affect your computer by altering the way it works without your knowledge or permission. In more technical terms, a virus is a segment of program code that implants itself to one of your executable files and spreads systematically from one file to another. Computer viruses must be written and have a specific purpose. Usually a virus has two distinct functions: spreads itself from one file to another without your input or knowledge and implements the symptom or damage planned by the perpetrator. This could include erasing a disk, corrupting your programs or just creating havoc on your computer.

Technically, this is known as the virus payload, which can be benign or malignant.

A benign virus is one that is designed to do no real damage to your computer. A malignant virus is one that attempts to inflict malicious damage to your computer, although the damage may not be intentional. There are a significant number of viruses that cause damage due to poor programming and outright bugs in the viral code. Some of the more malignant viruses will erase your entire hard disk, or delete files. Many of the currently known Macintosh viruses are not designed to do any damage. However, because of bugs (programming errors) within the virus, an infected system may behave erratically.

Computer viruses don't infect files on write-protected disks and don't infect documents, except in the case of Word macro viruses, which infect only documents and templates written in Word 6.0 or higher. They don't infect compressed files either. However, applications within a compressed file could have been infected before they were compressed. Viruses also don't infect computer hardware, such as monitors or computer chips; they only infect software. Finally, viruses don't necessarily let you know that they are there - even after they do something destructive.

Nowadays the number of viruses is about 55000. It increases constantly. New unknown types of viruses appear. To classify them becomes more and more difficult. In common they can be divided by three basic signs: a place of situating used operation system and work algorithms.

There are three groups of file infectors:

Viruses of the first group are called overwriting viruses because they overwrite their code into infected file erasing contents. But these viruses are primitive and they can be found very quickly.

The second group is called parasitic or cavity viruses. Infected file is capable of work fully or partly but contents of last one are changed. Viruses can copy itself into begin, middle or end of a file.

The third group is called companion viruses. They don't change files. They make double of infected file so when infected file is being started a double file becomes managing, it means virus.
