Three year anti-virus support:

For three years from the date you register your copy of Integrity Master,
Stiller Research will provide the following support at our expense:

 o If we discover a virus which can infect your PC and not be detected
   by Integrity Master, we will be notify you as soon as we confirm this
   threat.

   This refers to Integrity Master's ability to detect unknown viruses
   by detecting changes to affected executable files (i.e. *.EXE +
   *.COM) or boot sectors on your PC. THIS DOES NOT REFER TO
   NOTIFICATION EACH TIME A VIRUS APPEARS WHICH WE DO NOT RECOGNIZE BY
   NAME AS A KNOWN VIRUS.  Since new viruses appear daily, this would be
   unrealistic.

   Please read the chapter on detecting unknown viruses for details on how
   Integrity Master detects (new) unknown viruses.  Clearly, Integrity
   Master can't name and otherwise identify a newly created virus.
   (This virus won't even have a name until it is analyzed and a name is
   agreed upon.) (In many cases, new viruses STILL can be identified by
   name, since most new viruses are not really new but are modifications
   of existing viruses.  Integrity Master works by detecting certain core
   virus characteristics which are often still present in a modified
   virus.)

 o We will provide instructions on what precautions to take and deliver
   a version of Integrity Master designed to handle this virus as soon
   as it's available.

 o This offer applies only to the hardware upon which you originally
   installed Integrity Master and the DOS operating environment.
