- SCA (computer virus)
The SCA virus is the first
computer viruscreated for the Commodore Amigaand one of the first to gain public notoriety. It appeared in November 1987. The SCA virus is a boot sectorvirus. It features a line of text that appears at each and every 15th 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 !!
"SCA" is an
acronymfor the Swiss Cracking Association, a group engaged in software protection removal, so the geographic origin of the virus was Switzerland. The virus is probably authored by an SCA member known as "CHRIS".
SCA will not harm disks per-se, but spreads to any write-enabled floppies inserted. If they use custom bootblocks (such as games), they are rendered unusable. SCA also checksums as an original filesystem (OFS) bootblock, hence destroying newer filesystems if the user doesn't know the proper use of the "install" command to remove SCA ("install df0: FFS FORCE" to recover a 'fast filesystem' floppy).
The "Mega-Mighty SCA" produced the first Amiga virus checker which killed the SCA virus. This may well have been in response to estimates that approximately 40% of all Amiga users had SCA in their disk collection somewhere, due to rampant piracy.
Other authors inspired by the harmless SCA virus would later produce more destructive viruses known as the
Byte Banditand the Byte Warrior.
