I had one guy I’m the late 90s at my HS who made a program that copied itself onto every directory on the computer at startup. It was a .com file and if you tried to run it it would use the PC speakers to play a tone increasing in volume and pitch until it was unbearable. You had to do a hard boot to end it.
I also remember the Form virus that made the PC speakers make a sound each time you pressed a key. Can’t remember if it did anything else.
