Parity.a

This is a dangerous memory-resident boot virus. It hooks INT 9, 13h and infects floppy boot sectors and hard drive MBR on reading from these sectors. By using INT 9 (keyboard) this virus hooks warm reboot (Alt-Ctrl-Del) and calls INT 19h (reboot). Sometimes this virus decrypts and types the message “PARITY CHECK” and then hangs up the computer.
