A computer virus is a harmful program that can be made by individuals who intend to cause harm or disruption to systems and computers. They are hidden bits of code that connect to different programs or applications and once activated, they spread like wildfire. Typically, viruses can be found in a document or software that is downloaded from the internet or shared via email. Many countries consider it to be illegal to develop and spread viruses on computers.
There are many kinds of computer viruses that can be able to infect computers in various ways. Certain computer viruses are dependent on an application to start their work. Others are not dependent and can attack multiple systems without the need for a host. Computer viruses that employ a host program in order to infect computers are commonly called worms but those that do not employ this method of infection through other programs are known as viruses.
Certain viruses may begin to infect the system as soon as they arrive, whereas others remain undiscovered until a user is unaware of the code and executes it. The first computer virus was discovered in 1974, and it behaved much like a biological virus by rapidly multiplying itself and causing harm to the system. One example of an extremely destructive virus is the Stuxnet virus specifically designed to destroy computerized centrifuges utilized to enrich uranium.
The process of making viruses can be complex and is not suitable for those who are not experienced. However, it can be a fun and interesting method of testing your understanding of computer programming languages and systems. If you’re willing to invest the time and effort there are plenty of resources available that will teach you how to create viruses.
