A computer virus can be created maliciously by anyone who wishes to harm computers or systems. They are hidden bits of code that connect to other applications or programs, and, when activated, spread like wildfire. Viruses typically are attached to programs or documents that have been downloaded from the internet or sent via email. The majority of countries consider that the spreading of a computer virus is illegal.
In the world of computer viruses, there are a variety of varieties that can infect the system in various ways. Certain computer viruses depend on an application to begin their work. Others are independent and can attack several systems without a host. A computer virus that makes use of a host program to attack computers is often considered to be a worm, while those that do not employ the method of infection used by other programs are thought to be viruses.
Certain viruses can infect a system immediately upon entry, whereas others remain dormant and be activated when the user executes the code. The first computer virus was developed in 1974 and similar to biological viruses, grew quickly and caused damage to the system. One example of a destructive virus is the Stuxnet virus specifically designed to destroy computerized centrifuges utilized to enrich uranium.
The process of making a virus can be very complex and is not suitable for the faint of heart. It can be a fascinating way to test your computer programming knowledge. If you are willing to spend the time and effort there are plenty of sources that will guide you through the process of creating viruses.
