Silver Anniversary

At least according to Scientific American, the first computer virus was created twenty-five years ago, in 1982.

It ran on an Apple ][. I bought an Apple //e went it first came out, in 1983, but I never heard of this virus.

I seem to remember something about computer viruses in David Gerrold's When HARLIE was One (1972), but I may not have the correct reference. Certainly the idea of a computer virus was present before 1982, but it the development of the personal computer to make propagation possible.
