Stoned is a boot sector computer virus created in 1987. It is one of the first viruses and is thought to have been written by a student in Wellington, New Zealand.[1][2] By 1989 it had spread widely in New Zealand and Australia,[3] and variants became very common worldwide in the early 1990s.[4]
A computer infected with the original version had a one in eight probability[5][6] that the screen would declare: "Your PC is now Stoned!", a phrase found in infected boot sectors of infected floppy disks and master boot records of infected hard disks, along with the phrase "Legalise Marijuana". Later variants produced a range of other messages.
