A computer virus is a harmful program that is created by individuals who want to cause harm or disruption to systems and computers. They are coded bits that attach themselves to other programs or applications, and when activated, spread like wildfire. Typically, viruses are found attached to a document or program downloaded from the internet or shared via email. The majority of countries consider that the spreading of computer viruses is a crime.
There are many kinds of computer viruses that affect computers in different ways. Some depend on a program to begin their work and others are self-contained and are able to attack multiple systems without the need of an host. A computer virus that utilizes a host program to attack computers is often considered as a worm but those that don't use the method of infection by other programs are considered to be viruses.
Certain viruses infect systems immediately upon insertion, while others are inactive and only activate when https://kvbhel.org/news/why-is-online-advertising-good-for-your-business/ the user executes the code. The first computer virus was discovered in 1974, and it performed similar to a biological virus by rapidly multiplying itself and causing damage to the system. Stuxnet is an example of an extremely destructive computer virus. It was designed to destroy computerized centrifuges which were used to enrich the uranium content.
It is not for the weak-hearted to try this method. It can be a fascinating method to test your computer programming expertise. If you're willing to put in the effort and time there are a lot of resources available that will teach you how to create an infection.
