Believed to be the first virus released into the wild, the Elk Cloner reflected the camp spirit of the frontier days of computing in the early '80s. It was written by 15-year-old prankster Rich Skrenta for Apple II's DOS 3.3 operating system and passed a long on floppy disks to his friends. Unlike its modern descendents, the virus was more likely to annoy you than wreak havoc on your system. Those infected with Elk Cloner saw the following lymeric and heard a tune on every 50th boot: 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!
