Computer viruses can be frustrating at best and terrifying at worst if they compromise your personal information or credit cards!

BRAIN was created in 1986 by two Pakistani brothers, Basit Farooq and Amjad Alvi, who created and marketed medical software in Lahore, Pakistan. The two brothers were exploring the DOS operating system. They knew that the OS was vulnerable and wrote software that would enable them to track their products and minimize piracy.
