Apple II/Elk Cloner is also known as Elk Cloner.

Explanation :

Elk Cloner is one of the first known microcomputer viruses that spread "in the wild," i.e., outside the computer system or lab in which it was written. It was written around 1982 by a 15-year-old high school student named Rich Skrenta for Apple II systems.

Elk Cloner spread by infecting the Apple II operating system using a technique now known as a "boot sector" virus. If a computer booted from an infected floppy disk, a copy of the virus was placed in the computer's memory. When an uninfected disk was inserted into the computer, Elk Cloner would be copied to the disk, allowing it to spread from disk to disk.[5]

An infected computer would display a short poem on every 50th boot:
Elk Cloner: The program with a personality

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!


Elk Cloner did not cause deliberate harm, but Apple DOS disks without a standard image had their reserved tracks overwritten.
