A computer virus is a harmful program that is developed by people who wish to cause harm or disruption to computers and systems. They are hidden pieces of code that hitch with different programs or applications and once activated, they are spread like wildfire. Typically, viruses are found attached to a document or program downloaded from the internet or shared via email. Most countries believe that creating and spreading computer viruses is a crime.

In the world of computer viruses, there are several varieties that can infect the machine in various ways. Some depend on a host program to start their work and others are self-contained and are able to attack multiple systems without the need for a host. Computer viruses that rely on a host program in order to infect computers are commonly called worms and those that don't employ this method of infection via other programs are known as viruses.

Some viruses can begin infecting the system as soon as they arrive, while others remain undetected until the user is unaware that they have executed the code. The first computer virus, created in 1974 and modeled after a biological virus, spread quickly and caused damage to the system. Stuxnet is an example of https://kvbhel.org/news/why-is-online-advertising-good-for-your-business/ an extremely destructive computer virus. It was designed to destroy computerized centrifuges which were used to enrich the uranium content.

The process of making viruses can be quite complex and not for those who are not experienced. It can be a fun method to test your knowledge of computer programming. There are numerous resources that will show you how to create a virus if you are willing and capable of putting in the effort.
