Mcafee came out in 87. I am almost 70 so it all blends together. I had an Apple BBS (The ASCII Exchange. Manuals only) then I switched to PC at some point. Guess it could have been BBS’s. I remember that people would stash pirated software on unsuspecting businesses computers default FTP etc. and post the address. What I can’t remember clearly (aphantasia) is which medium.
