A computer virus is a harmful program that can be made by those who want to cause damage or disruption to systems and computers. They are hidden bits of code that connect to other programs or applications, and, when activated, spread like wildfire. Typically, viruses are discovered in a document or program downloaded from the internet or distributed via email. The majority of countries believe that the spreading of computer viruses is a crime.
There are many kinds of computer viruses that attack computers in a variety of ways. Some depend on a program to begin their work and others are self-contained and can attack multiple systems without the need for the host. Computer viruses that rely on host programs to infect computers are often called worms however, those that do not use this method of infecting through other programs are known as viruses.
Certain viruses may begin to infect systems as soon as they are discovered, while other is total av safe for all business remain inactive until the user is unaware of the code and executes it. The first computer virus was developed in 1974, and it behaved similar to a biological virus by multiplying itself rapidly and causing damage to the system. One example of a destructive virus is the Stuxnet virus that was specifically created to destroy computerized centrifuges that were used to enrich the uranium.
It isn’t for the weak-hearted to try this kind of process. However it can be a great and interesting method of testing your proficiency in computer programming languages and systems. There are many resources that will show you how to create a virus if you are willing and capable of putting into the effort.
