This year marks the 25 year existence of the notorious computer virus. Most likely the first question that would cross your mind would be, “What was the first computer virus?” or “Who created the first computer virus?” right?
Well, did you know that the first ever computer virus created was created for an Apple system. Yup, you read that right. The virus was called the “Elk Cloner“.
Elk Cloner is the first known computer virus that has 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’s operating system, stored on floppy disks. When the computer was booted from an infected floppy, a copy of the virus would automatically start. Apart from monitoring disk access, the virus would not normally alter the workings of the computer. When an uninfected floppy was accessed, the virus would copy itself to the disk, thus infecting it, too, slowly spreading from floppy to floppy.
Like many of the early viruses, Elk Cloner did not cause any deliberate harm, although it could harm disks not containing the standard DOS image – it overwrote its reserved tracks regardless of the contents. Like many of the early viruses, however, it did cause annoyance: on every 50th booting the virus would display a short “poem,” as follows:
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!Annoyance, in fact, was the reason for the virus’s existence. Skrenta previously had the habit of giving out pirated computer games to his friends, but games modified such that they would stop working after a given number of games. This scheme guaranteed a high level of annoyance: by the time those friends grew to like the programs the programs would stop working, usually with some “humorous” message (at least as judged by their author). After a while those friends learned never to allow Skrenta near their disks. Then came Cloner, which could annoy friends without Skrenta physically gaining access to their disks.
According to contemporary reports, the virus was rather contagious, successfully infecting the floppies of most people Skrenta knew (including his math teacher), upsetting many of them (including said math teacher). Part of the “success,” of course, was that people were not at all wary of the potential problem (virus infection could have been avoided by not inserting floppies into computers without hard-booting them before), nor were virus scanners or cleaners available. The virus could still be removed, but it required an elaborate manual effort.

So put out the cake and start singing “Happy Birthday Computer Virus”! Hehe..
Anyways, now is a good time to remind everyone to practice safe computing and keep your antivirus up-to-date!
Hat tip to my friend Donjun.
Actually every operating system is in danger of malwares. Virus authors are looking for crowded places to spread their mals like virus.
@K – I’m not sure I know what you’re talking about. Can you be more specific? All I can think of is the Windows Update notification icon on the system bar.
Remember whenever you open your Win XP, there’s this little icon for Microsoft upgrade or your pc will crash? It’s annoying. :mad:
I didn’t know much about the early Macs, so thank you for sharing the info. Now that I’m using OSX, that means, it’s virus free.
@jhay – Haha..you can say that too. :D
Or a disk that needs a second life. :lol:
@fruityoaty – a floppy disk is a disk that needs Viagra. LOL :D
Floppy disk? What’s a floppy? :p
