UTIL APR91 PCCanary Schenot Virus Detector Alarm Security ASP
FILES: cny91e.sdn

Update

Virus alarm  which  detects  modifications  to .EXE, .DAT and
COMMAND.COM files.   Installs  easily  and  does  not  modify
files, allowing its use with other security programs.  Allows
DOS upgrades.  Named for miner's canary whose death signalled
invisible toxic fumes.

For centuries,  miners  have  brought  a canary down into the
mines with them.  They do not do this for the company or  for
the  music;  they  do it because a canary will die from small
amounts of deadly gasses prior to the miner  feeling  adverse
effects.   Installed  and used properly, The PC Canary may be
one of the first programs to become infected  by  a  computer
virus,  and  will  give  you  enough warning to eradicate the
virus and recover before the virus does serious damage.

This program scans itself, its data file, and COMMAND.COM for
infection by a computer virus.  The PC Canary scans  for  all
types  of  computer  virus  that infect .exe programs or .dat
files, ie., virtually all viruses.  It is able to scan itself
even for viruses that haven't  been  written  yet,  since  it
detects  the  effects  of  the  virus  rather  than the virus
itself.

Advantages of a passive virus detector include:

  * Low maintenance.  Since it detects  the  effects,  rather
    than  the  signature  of  a virus, it is not necessary to
    constantly update the software for new virus strains.

  * Low overhead.  It is not memory-resident, and so does not
    require CPU cycles and memory.  Since it need scan only a
    limited number of  files  for  known  results,  it  takes
    little  processing time as compared to programs that scan
    all files for matches on a signature table of  more  than
    200 possible viruses.

A smoke alarm, not a fire extinguisher.
