It is not a dangerous memory resident parasitic polymorphic virus.
It hooks INT 1Ch, 21h and writes itself to the end of COM and EXE files
that are executed or opened. If there is long period of keyboard inactivity
this virus draws the picture of death’s head with the text “PHANTOM 1” and
displays the message:
Congradulations!!! Your computer is now infected with a high performance
PHANTOM virus! Coming soon: next virii based on the _C00LEST_ mutation
engine all over the world: the Advanced Polymorphic Engine! Enjoy this
intro! (C) 1994 by Dark Prince.
This virus has bugs. Sometimes it corrupts the files while infecting:
the decryption routine cannot decrypt the virus body. While executing these
files halt the system. Second, the video effect does not work under
MS-Windows, Win95 and different memory managers.
