A computer virus is a harmful program that can be created by individuals who want to cause damage or disruption to computers and systems. They are hidden bits of code that ride an ride on other applications or programs and when activated they propagate like wildfire. Typically, viruses can be discovered in a document or program that is downloaded from the internet or sent via email. Most countries believe that the spreading of computer viruses is a crime.
There are a myriad of types of computer viruses that attack computers in data room provider a variety of ways. Some are dependent on a program to start their work and others are self-contained and can attack multiple systems without the need of a host. A computer virus that utilizes a host program to infect computers is typically considered to be a worm however, those that do not employ the method of infection used through other programs are deemed to be viruses.
Certain viruses may begin to infect systems as soon they arrive, whereas others remain inactive until the user accidentally executes the code. The first computer virus was discovered in 1974, and it performed as a biological virus by rapidly multiplying itself and causing damage to the system. One example of an extremely destructive virus is the Stuxnet virus specifically designed to destroy computerized centrifuges used to enrich uranium.
It is not for the faint-hearted to attempt this kind of process. However it can be an enjoyable and interesting way to test your understanding of computer programming languages and systems. If you are willing to put in the effort and time there are plenty of resources available that will guide you through the process of creating an infection.
