Ever since the first self-copying, malicious computer program was introduced into computers in 1986 virus have caused many problems. They can slow down the machine or corrupt data, show funny or political messages, access personal information such as credit card numbers telephone numbers, passwords, phone numbers and bank accounts, spam the user’s email contacts and e-mail addresses, even make the machine inaccessible.

A virus is a fragment of code that binds itself to other files and programs, and then spreads through explanation infecting them and hiding until the affected program can be run. Typically, a virus begins by infecting the host program, and then spreads to other programs and files, mostly via e-mail. A virus that is successful can cause significant damage and destruction within an extremely short period of time.

Creating a virus requires the time and skills, but anyone who is interested in computer programming can discover how to make virus. The process of creating a virus can be done for the purpose of learning about a programming language, or simply as a fun prank. The process of creating a virus can be a great way to test the effectiveness of an antivirus scanner.

This article will demonstrate how to build a simple computer virus using Python. The same process can also be used with any other programming language. Python is a suitable programming language for beginners since it is easy to master and relatively fast. For viruses, other programming languages that can be compiled are typically preferred because they work at an lower level of the computer and will therefore be more efficient.
