The first widespread virus for an IBM PC operating system was called Brain. Like Elk Cloner, it was also a boot sector virus, although its creators had little in common with Skrenta. Pakistani brothers Basit and Amjad Farooq Alvi say they had't heard of him or Elk Cloner when they wrote Brain in 1986.

Infected disks usually have five kilobytes of bad sectors. The disk labels is usually change to ©Brain, and the following text can be Show in infected boot sectors:-
