High Quality Content by WIKIPEDIA articles! The Michelangelo virus is a computer virus first discovered in April 1991 in New Zealand. The virus was designed to infect DOS systems, but did not engage the operating system or make any OS calls. Michelangelo, like all boot sector viruses, basically operated at the BIOS level. Each year, the virus remained dormant until March 6, the birthday of Renaissance artist Michelangelo. There is no reference to the artist in the virus, and it is doubtful that the virus writer intended Michelangelo to be referenced to the virus. Michelangelo is a variant of the already endemic Stoned virus.
