   60% Parity Family

    Summary: Parity Family. These are dangerous
    memory resident Boot-viruses. They hook INT 9, 13h
    and infect floppy Boot-sectors and hard drive MBR
    on reading from these sectors. By using INT 9
    (keyboard) these viruses hook warm reboot
    (Alt-Ctrl-Del) and call INT 19h (reboot). Sometimes

    "Clock" also hooks INT 8, ...
