A computer virus can be created maliciously by anyone who wishes to damage systems or computers. They are hidden bits of code that are attached to other applications or programs, and, when activated, spread like wildfire. Typically, viruses are discovered in a document or program that has been downloaded from the internet or sent via email. The majority of countries think that the creation and spread of the virus on computers is illegal.
In the world of computer virus, there are different kinds of viruses that can affect the machine in various ways. Some are dependent on a program to begin their work, while others are not dependent and are able to attack multiple systems without the need of hosting. A computer virus that uses host programs to infect computers is often considered as a worm while those that do not utilize the method of infection by other programs are believed to be viruses.
Some viruses can begin infecting systems as soon as they arrive, whereas other remain undetected until the user is unaware of the code and executes it. The first computer virus, developed in 1974 and identical to a biological virus, spread rapidly and caused harm to the system. One example of damaging viruses is the Stuxnet virus specifically designed to destroy computerized centrifuges that were used to enrich the uranium.
The process of making a virus can be very complex and is not suitable for those who are not experienced. It can be a fascinating way to test your computer programming skills. There are numerous sources that can help you understand how to create a virus, if you are willing and willing to put into the effort.
