It is a program that can enter a computer in many different ways. These programs, viruses, are special programs in that they can cause unwanted or damaging effects. Once a virus manages to enter a computer, it will situate itself in places where it can be run, unintentionally, by the user. A virus will not act until it has been run or until certain pre-established conditions have been met -trigger condition (a specific date, an operation carried out by the user, etc.). In some cases, the effects produced by a virus, known as the virus payload, will not be seen until some time after it has infected the computer. A typical characteristic of viruses is their capacity to reproduce and spread to other files or programs. Computer viruses are called viruses due to their similarities with biological viruses. In the same way as biological viruses enter the body and infect the cells, computer viruses get into the into the computer and infect files. In addition, both types of virus can reproduce themselves and spread, passing the infection from one infected system to others.
The effects produced by a virus can be destructive or simply annoying: they can damage or delete data stored in a computer, cause the infected computer to crash, display on-screen messages, etc.
In addition to propagation and infection techniques, viruses also use 'evasion' techniques. This means that the virus has techniques or a defense system that makes it difficult to detect it and helps it avoid any action taken against it.
