elk cloner is one of the first known microcomputer viruses that spread "in the wild", "i.e.", outside the computer system or laboratory in which it was written. it attached itself to the apple ii operating system and spread by floppy disk. it was written around 1982 by programmer and entrepreneur rich skrenta as a 15-year-old high school student, originally as a joke, and put onto a game disk.

elk cloner
in 1982, a program called "elk cloner" was the first personal computer virus to appear "in the wild"—that is, outside the single computer or [computer] lab where it was created. written in 1981 by richard skrenta, a ninth grader at mount lebanon high school near pittsburgh, it attached itself to the apple dos 3.3 operating system and spread via floppy disk. on its 50th use the elk cloner virus would be activated, infecting the personal computer and displaying a short poem beginning "elk cloner: the program with a personality." in 1984 fred cohen from the university of southern california wrote his paper "computer viruses – theory and experiments". it was the first paper to explicitly call a self-reproducing program a "virus", a term introduced by cohen's mentor leonard adleman. in 1987, fred cohen published a demonstration that there is no algorithm that can perfectly detect all possible viruses. fred cohen's theoretical compression virus was an example of a virus which was not malicious software (malware), but was putatively benevolent (well-intentioned). however, antivirus professionals do not accept the concept of "benevolent viruses", as any desired function can be implemented without involving a virus (automatic compression, for instance, is available under the windows operating system at the choice of the user). any virus will by definition make unauthorised changes to a computer, which is undesirable even if no damage is done or intended. on page one of "dr solomon's virus encyclopaedia", the undesirability of viruses, even those that do nothing but reproduce, is thoroughly explained.
