In 1986, brothers Basit Farooq Alvi and Amjad Farooq Alvi created the Brain virus, considered to be the first virus for MS-DOS.

Based out of Lahore, Pakistan, the brothers were trying to protect their medical software from piracy. Users would receive the message:

"Welcome to the Dungeon © 1986 Brain & Amjads (pvt). BRAIN COMPUTER SERVICES 730 NIZAM BLOCK ALLAMA IQBAL TOWN LAHORE-PAKISTAN PHONE: 430791,443248,280530. Beware of this VIRUS.... Contact us for vaccination..."

Today, the brothers have a company named Brain Telecommunications Ltd and provide a variety of computer-related services.
