A computer virus can be developed maliciously by anyone wanting to cause harm to systems or computers. They are hidden pieces of code that ride a ride on other applications or programs and when activated they propagate like wildfire. Viruses are often found attached to documents or programs that have been downloaded from the internet or distributed via email. Most countries believe that the creation and spread of a computer virus is illegal.
There are a variety of computer viruses which can affect computers in different ways. Certain computer viruses rely on an application to start their work. Others are independent and can infect multiple systems without a host. Computer viruses that utilize a host program in order to infect computers are usually referred to as worms, but those that do not employ this method of infection by using other programs are referred to as viruses.
Certain viruses can infect a system immediately upon insertion, while others remain dormant and become active when the user executes the code. The first computer virus was developed in 1974, and it behaved similar to a biological virus by multiplying itself rapidly and damaging the system. One example of a destructive virus is the Stuxnet virus, which was specifically designed to destroy computerized centrifuges that were used to enrich uranium.
The process of creating viruses can be extremely complicated and is not for the faint of heart. However it can be an enjoyable and interesting way to test your understanding of computer programming languages and systems. There are data room provider a lot of resources that can show you how to create a virus if you are willing and willing to put in the effort.
