How to Make a Computer Virus

A computer virus is a malicious program that is developed by individuals who want to cause harm or disruption to systems and computers. They are hidden pieces of code that ride an ride on other programs or applications, and once activated they can spread like wildfire. Viruses typically are attached to documents or programs that have been downloaded from the internet or sent via email. Many countries consider it to be illegal to create and spread viruses on computers.

There are a myriad of types of computer viruses that are able to infect machines in different ways. Some depend on a host program to start their work, while others are independent and are able to attack multiple systems without the need of a host. Computer viruses that rely on a host program in order to infect computers are typically known as worms however, those that do not use this method of infection via other programs are known as viruses.

Certain viruses infect a system immediately upon arrival, while others remain dormant, and only activate after the user executes the code. The first computer virus was developed in 1974, and akin to biological viruses, grew rapidly and caused harm to the system. Stuxnet is an example of a destructive computer virus. It was designed to destroy computerized centrifuges which were used to enrich Uranium.

It isn’t for the weak to attempt this process. It can be a fun method to test your computer programming knowledge. There are numerous resources that can show you how to create a virus if are willing and able to put into the effort.
