SCA virus

The SCA virus was the first computer virus created for the Commodore Amiga. It appeared in November 1987. The SCA virus was a boot sector virus. It featured a quite famous line of text that appeared at 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 acronym for the Swiss Cracking Association , a group engaged in software protection removal, so the geographic origin of the virus was Switzerland. The virus was probably authored by an SCA member known as "CHRIS".

SCA would not harm disks per-se, but would spread to any write-enabled floppies inserted. If they used custom bootblocks (such as games), they would be rendered unusable. SCA also checksums as an original filesystem (OFS) bootblock so will destroy newer filesystems.

The "Mega-Mighty SCA" produced the first Amiga virus checker (Later named "antivirus" on Windows systems) which killed the SCA virus.

Other authors inspired by the harmless SCA virus would later produce more destructive viruses known as the Byte Bandit and the Byte Warrior .
