It was 25 years ago the first computer virus was born, surprisingly it was for a Mac. In 1982 a tech savvy ninth grader named Richard Skrenta got an Apple II for Christmas and decided to play a joke on his friends and the first computer virus was born. He put it on a game as it attached itself to the Apple DOS 3.3 operating system and spread by floppy disk.The game was set to play, but release the virus on the 50th time of starting the game. Instead of playing the game the screen would go blank and read a poem about the virus named Elk Cloner.

It will get on all your disks
It will infiltrate your chips
Yes it's Cloner!

It will stick to you like glue
It will modify RAM too
Send in the Cloner!

The virus did not do much damage as it copied itself to other disks.

The first PC virus was created four years later in 1986 by two brothers in Pakistan, Basit and Amjad Farooq Alvi.
The first commercial anti virus package Dr. Solomon's Anti-Virus Toolkit was released by Briton Alan Solomon by fall of 1988.
Computer viruses have evolved into much dangerous avatars since its humble beginnings 25 years ago, with smart mobile phones making an appearance the virus is long but gone.
