A computer virus can be created maliciously by anyone wanting to harm computers or systems. They are hidden bits of code that connect to other programs or applications, and, when activated, spread like wildfire. Viruses are often found on documents or programs that were 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 several kinds that can infect a machine in different ways. Certain computer viruses depend on an application to start their work. Others are not dependent and are able to attack multiple systems without the need for a host. A computer virus that relies on a host program to infect computers is often considered to be a worm, and those that do not use the method of infection by other programs are believed to be viruses.
Certain viruses can begin infecting systems as soon they arrive, while others remain undetected until the user is unaware of the code and executes it. The first computer virus was discovered in 1974 and behaved similar to a biological virus by rapidly multiplying itself and causing damage to the system. One example of a destructive virus is Stuxnet virus specifically designed to destroy computerized centrifuges utilized to enrich uranium.
It isn’t for the weak-hearted to try this task. However, it is a fun 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 many resources that can show you how to make viruses.
