Back in 1999, the viral game Elf Bowling gained an unfounded, false reputation as a piece of malware and spyware. It was viral, but it wasn’t a virus.
The original piece of ransomware involved AIDS researchers, an evolutionary biologist, and a P.O. Box in Panama. Oh, and butterflies.
The computer virus has been around for more than 40 years now, and it's caused lots of panic (and occasionally some damage) over the years. But don't freak.
