Since the first malicious, self-copying computer program slipped into computers in 1986 the virus has been causing many issues. They can slow down a machine and cause data corruption or display funny or political messages. They can also obtain personal information, such as credit card numbers, telephone number or passwords, bank accounts and spam email addresses and contacts.

A virus is a program that attaches itself to other files or programs, infects them and remains hidden until the infected software is run. The virus typically starts by infecting a host application and then spreading through email to other programs and data files. A virus that is successful could cause a great deal of damage and destruction within an extremely short period of time.

Creating a virus requires patience and experience, but anyone who is interested in computer programming can learn how to create viruses. Creating a virus can be done with the intention of learning about a programming language, or even as a prank. Creating a virus can also be a good way to test the effectiveness of an antivirus scanner.

This article will explain how to create a simple computer virus using Python however the same technique can be applied to any programming language. Python is a great programming language for beginners, because it’s relatively easy to master. For viruses other programming languages that can be compiled are generally preferred since they operate at lower levels of the computer and consequently be more efficient.
