They are coded bits that are attached to different programs or applications and once activated, they spread like wildfire. Viruses are usually found attached to programs or documents that were downloaded from the Internet or distributed via email. Most countries consider it illegal to create and spread a computer virus.

Some depend on a host program to start their work, while others are not dependent and are able to attack multiple systems without the need for the host. A computer virus that makes use of a host program to infect computers www.kvbhel.org/mobile/4-golden-rules-to-choosing-the-right-online-business-opportunity/ is usually considered to be a worm however, those that do not utilize the method of infection by other programs are thought to be viruses.

The first computer virus was discovered in 1974 and behaved like a biological one by rapidly multiplying itself and damaging the system. Stuxnet is an example of a destructive computer virus. It was created to destroy computerized centrifuges which were used to enrich the uranium.
The process of making a virus can be very complex and not for those who are not experienced. It is a great method to test your computer programming skills. If you’re willing spend the time and effort, there are many sources available to guide you through the process of creating viruses.
