SENTRY is  a  computer  virus  detection  system that catches
viruses that have  entered  your  system.   It  uses  a  high
reliability  detection  mechanism  that  monitors  all system
areas that are susceptible to viral attacks.  If a virus does
enter your system, SENTRY will identify the  specific  system
area  or program files that have been infected, so that virus
removal is simplified.

SENTRY executes in two phases.   The  initial  install  phase
logs the   system's   hardware   and  software  parameters  -
including the initial interrupt vector  states,  boot  sector
instructions,  hidden  DOS  files,  device  drivers  and  all
executable  code   on   the   hard   disks.    Initial   load
instructions,  branch addresses, and other program states are
also  logged  for  each  program  on  the  hard  disk.    The
subsequent  check  phase  executes  each  time  the system is
powered on or re-booted, and it checks all system  parameters
for traces of infection.

SENTRY is  fully  effective  in  detecting viruses, including
boot sector infectors and imbedded viruses (viruses that  the
leave  the  infected  program's  size and external indicators
unchanged).   It  provides  a  timely  and   near   foolproof
indication of infection.
