-
- History: This virus was first reported in Wellington, New Zealand in
- early 1988.
-
- Description of Operation: This virus consists of a boot sector only. It
- infects any disk inserted in a drive after it becomes activated during a
- boot, and it occupies 1K of memory. The original boot sector is held in
- track zero, head one, sector three on a floppy disk, and track zero, head
- zero, sector two on a hard disk. The boot sector contains two character
- strings: "Your PC is now Stoned!" and "LEGALISE MARIJUANA!". The first
- of these messages is only displayed one in eight times when booting from
- an infected floppy, the second is unreferenced. In some variations, the
- message is displayed on every 32nd boot.
-
- In the original version of this virus, only 360 KB 5 1/4" floppies
- were infected. While the original version was unable to infect a hard
- disk, other versions (such as New Zealand B) are capable of doing so.
-
- The virus can (unintentionally) trash 1.2 Mb floppies if they have
- more than 32 files, and trashes about 5% of hard disks.<Note: Dr. Alan
- Solomon. "The Information Center - PC Security", 1989.>
-
- Removal: The Stoned virus can be removed from 360KB diskettes by using
- either the MDisk, CleanUp, or F-Prot programs. It can also be removed
- from diskettes by using the DOS SYS command. Be sure to power down your
- system and reboot from a clean, write-protected floppy prior to
- attempting disinfection.
