I only know of one for the C64, which was called, "HIV".Frank wrote:I know the c64 and Amiga's had quite a few.

A virus requires that the hardware remain running while disk-accessing software is running, and media is being swapped.
With the old Commodore 8-bit machines, the computer was often switched off and on when software was changed. Also, disk reads and writes weren't constantly taking place as is common on current computers. Also, 6502 code was generally not relocatable, and each piece of software managed the machine's memory in its own way, eliminating a vulnerability that many viruses exploit. In short, the old Commodore machines were designed to run one program at a time.
Now I suppose that a virus could be written to the 1541's RAM, which would be more stable because Commodore users probably didn't switch of the disk drive as often as the main unit.
