How did internet viruses spread before the internet was invented!
They didn’t as they didn’t exist yet.
Non-internet viruses spread through other kinds of networks or by physically installing them from portable media.
(Real answer: The first virus was made in 1971 and was spread much the same way now, over ARPANET, the “proto-internet”. It was called Creeper. So technically, there were no viruses before the invention of the internet)
