I had one guy in 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 ran 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.
Thanks for the information. Interesting reading up on this experiment. Wikipedia have several good sources. Seems many of these people forget the "personal responsibility" part of their (deranged) ideology.
