The SCA virus is the first computer virus created for the Commodore Amiga and one of the first to gain public notoriety. It appeared in November 1987. The SCA virus is a boot sector virus. It features a line of text that appears at every 15th copy after a warm reboot:
Something wonderful has happened Your AMIGA is alive !!! and, even better… Some of your disks are infected by a VIRUS !!! Another masterpiece of The Mega-Mighty SCA !!
Elk Cloner (1982) was written by a 15 year old high school student called Rich Skrenta as a practical joke. The virus was developed for the Apple II system and was a boot sector virus that spread via floppy discs (mostly through pirated games).
The Ping-Pong virus (also called Boot, Bouncing Ball, Bouncing Dot, Italian, Italian-A or VeraCruz) is a boot sector virus discovered on March 1, 1988 at the University of Turin in Italy. The virus would become active if a disk access is made exactly on the half hour and start to show a small “ball” bouncing around the screen in both text mode (the ASCII bullet character “•”) and graphical mode.
The SCA Virus was probably the first Amiga virus (1987). It became extremely common, and later SCA released a software to remove the virus.
There were many clones of the virus with cool names like 666, AIDS, Bad Bytes 4, Big Boss, Deniz Cool, Disk-Terminator, KarlMarx, LSD, MAX and NASA.
