BO was the only malware I got infected with on Windows. Back in 99, some colleague had sent me an executable to try out (supposed to be the portscan tool he developed), it did nothing so he said "hmm ok". Later, my mouse started becoming erratic, I started to make typos. I finally figured out what's going on when the CD drive ejected itself and I shut off the computer. He later admitted messing around.
