It is a very dangerous memory resident encrypted parasitic virus. It hooks INT 10h, 17h, 21h and writes itself to the end of COM and EXE files that are executed. On opening .C, .CPP, .PAS, .TXT and .PRG files the virus overwrites them with the text:
This virus is a publicity stunt
of the DOG SQUAD (CSE 93 Batch of RECJ)
and has been issued in public interest by
the Registar of the Squad.
Long Live N.P.
The virus disables printing (INT 17h) and several graphic video modes (INT 10h).
