A computer virus can be created maliciously by anyone who wants to cause harm to computers or systems. They are hidden bits of code that are attached to other applications or programs, and when activated, spread like wildfire. Viruses are usually found in documents or programs that were downloaded from the internet or distributed via email. The majority of countries think that creating and spreading the virus on computers is illegal.
In the world of computer viruses, there are several different types that can infect a machine in different ways. Certain viruses are dependent on a program to start their work however, others are completely independent and can attack multiple systems without the need of a host. A computer virus that utilizes a host program to infect computers is often considered to be a worm, however, those that do not utilize the method of infection by other programs are thought to be viruses.
Certain viruses may begin to infect systems as soon they arrive, whereas other remain dormant until the user is unaware that they have executed the code. The first computer virus, created in 1974 and modeled after a biological virus, multiplied rapidly and caused harm to the system. One example of an extremely destructive virus is the Stuxnet virus, which was specifically designed to destroy computerized centrifuges utilized to enrich uranium.
It isn’t for the weak-hearted to attempt this process. It can be a fun way to test your computer programming knowledge. There are a lot of sources that can help you understand how to create a virus if you are willing and capable of putting into the effort.
