  Computer viruses are a menace to the computer software industry.  This
  program is designed to help combat that menace.  All 'PC Learning Games'
  programs are developed on PCs with sophisticated virus detection software,
  so you can be sure that the original disks were virus free.  However,  as
  these programs are distributed as "shareware", it is possible that the
  programs can become infected as they are copied between different users.

  VCHECK.EXE will check, that as far as is possible, the programs are the
  same as the originals.

  PLEASE NOTE: VCHECK.EXE is NOT a complete virus detection system.  It does
  not recognize specific viruses, but detects the effect of any virus on 'PC
  Learning Games' .EXE files.  It can not detect viruses infecting other
  programs or disks.  There are many commercially available products that
  will scan for and detect viruses.  I would recommend VIRUSCAN from

  VCHECK.EXE calculates a checksum for all PC Learning Games programs that it
  finds in the current directory.  If the calculated checksum doesn't match
  the stored checksum then a warning is given.  The reasons that a checksum
  might not match are:

  1.   A virus has attached itself to the file.

  2.   A program file is corrupt.

  3.   The version of VCHECK.EXE is for a different version of the programs.

  If your disk does not contain VCHECK.EXE, or if VCHECK.EXE reports any of
  the above, DO NOT RUN THE PROGRAMS.  Write for a clean copy of the disk to:
