The world first learned what a computer virus was in 1986. It was written by two brothers, Basit and Amjad Farooq Alvi, for a Windows-based PC. This virus is called "Brain," It was created to adjust and protect the software. After the pirate version of the virus spread worldwide, the media went crazy with the number of notifications of infected computers but initiated no criminal proceedings against the creators. Finally, in 1987, an outbreak prompted IBM to create the first antivirus for a wide range of users.
