A computer virus is a malicious program that can be made by people who wish to cause harm or disruption to systems and computers. They are hidden bits of code that hitch an ride on other programs or applications, and when activated they spread like wildfire. Typically, viruses are discovered attached to a file or program that is downloaded from the internet or distributed via email. The majority of countries consider that the creation and spread of computer viruses is a crime.
In the world of computer viruses, there are a variety of varieties that can infect the machine in various ways. Some depend on a host program to begin their work, while others are independent and can infect multiple systems without the need of a host. Computer viruses that rely on host programs to infect computers are usually known as worms while those that don’t use this method of infection via other programs are referred to as viruses.
Certain viruses infect a system immediately upon entry, whereas others are dormant and only activate when the user executes the code. The first computer virus was discovered in 1974, and it acted as a biological virus www.kvbhel.org/news/why-is-online-advertising-good-for-your-business/ by rapidly multiplying itself and damaging the system. One example of an extremely destructive virus is the Stuxnet virus specifically designed to destroy computerized centrifuges used to enrich uranium.
It isn’t for the weak to attempt this kind of process. However, it can be a great and exciting way to test your knowledge of computer programming languages and systems. If you are willing to take the time and effort you can find a variety of sources available to help you create viruses.
