A computer virus is a malicious program that is created by people who wish to cause damage or disruption to computers and systems. They are hidden bits of code that hitch an ride on other applications or programs and when activated, they propagate like wildfire. Typically, viruses are discovered attached to a file or program that has been downloaded from the internet or sent via email. The majority of countries consider it illegal to create and distribute viruses on computers.

In the world of computer viruses, there are several different kinds of viruses that can affect the machine in various ways. Certain computer viruses rely on an application to start their work. Others are self-contained and are able to attack multiple systems without the need for a host. Computer viruses that use a host program in order to infect computers international employment contracts are usually known as worms however, those that do not use this method of infection via other programs are known as viruses.

Certain viruses infect systems immediately upon entry, whereas others remain dormant, and only activate when the user executes the code. The first computer virus, created in 1974 and similar to a biological virus, spread itself quickly and caused damage to the system. One example of an extremely destructive virus is the Stuxnet virus specially designed to destroy computerized centrifuges used to enrich the uranium.

It isn’t for the weak-hearted to attempt this process. It can be a fun method to test your computer programming expertise. If you’re willing put in the effort and time you can find a variety of sources that will help you create an infection.
