How to Make a Computer Virus

Since 1986 when the first malware-based self-copying program entered computers viruses have caused all sorts of issues. They can cause a machine to slow down or corrupt data or display funny or political messages. They can also obtain personal information, such as credit card numbers, telephone number passwords, bank accounts, passwords and spam email addresses as well as contacts.

A virus is a small piece of code that attaches to other files and programs, and then spreads through infecting them, hiding until the affected program can be run. Typically, a virus begins by infecting the host application and then expands to other programs and files, typically via e-mail. A successful virus can cause many damages and destruction within a short period of time.

It takes time and expertise to create viruses on computers, but anyone interested in programming for computers will be able learn how. Making a virus could be done with the intention of learning about a programming language, or simply as a fun prank. Creating a virus can also be a good way to test the effectiveness of an antivirus scanner.

This article will explain how to make a simple computer virus using Python however the same method can be used for any programming language. Python is a good programming language for beginners because it is easy to learn and is relatively quick. For viruses, other programming languages that can be compiled are typically preferred since they operate at lower levels of the computer and will consequently be more efficient.
