                                                                                
                  A list of quick informational notes.                          
                  ------------------------------------                          
                                                                                
McAfee's VirusScan version 1.x.x is no longer supported internally by 
THDPRO.EXE. If you wish to use the 1 series from McAfee, you will need to 
configure it for use through THDEXARC. I am of the opinion that the 1 series 
by McAfee is too far out of date to be considered useful. 

If files constantly fail the scan, ensure that there is enough available 
memory.

Network Users are strongly recommended to rename THDINSTL.EXE to NETINSTL.EXE
(or optionally run THDINSTL.EXE /NET). You should also take a moment to read
"Network Notes" in THDDOC.TXT.

When running The DOS version of THDPRO.EXE from a BBS, be sure that your BBS 
is swapping it's memory out to DISK/EMS/XMS (see your BBS documentation for 
swapping options) or risk failing of files due to insufficient memory to load 
scanners and archive utilities.

If using Scan 2.x.x be sure that *.DAT files are located in the same directory
as SCAN.EXE. (Subject to change, see this program's documentation)

If using F-PROT be sure the file ENGLISH.TX0 (or other TX0 file) and SIGN.DEF
are in the same directory as F-PROT.EXE. (Subject to change, see this
program's documentation)

If using TBSCAN.EXE be sure that TBSCAN.DAT and TBSCAN.SIG are located in the
same directory as TBSCAN.EXE. (Subject to change, see this program's
documentation)

For MULTI-NODE BBS'es set comports to "0" and pass the needed comport on the
command line whenever possible.

If Secure Mode is used, you must run THDPRO.EXE /SEC to initiate/update the
THDPRO.SEC file after each utility update or reconfiguration. Failure to do so
will cause unwarranted failures. If THDPRO.EXE is renamed, it will create a
file whose name matches the new name of THDPRO.EXE with the extension ".SEC"
(thus allowing multiple copies of both THDPRO.EXE and THDPRO.SEC to reside in
the same directory) ie. If THDPRO.EXE were renamed to "NEWTHD.EXE" then
running NEWTHD.EXE /SEC would produce the file NEWTHD.SEC.
    Note that if the THDEXARC format is used with SECURE mode the file entries 
must be edited in THDEXARC in order to update their CRC's when changes are 
made as THDPRO /SEC does not update the THDEXARC.DAT file.


Command line options (except comport[DOS] or file handle[OS/2]) will override 
the "default configuration".

Run THDINSTL.EXE for AUTHOR contact information.

PARAMETERS -
----------

/ADD - for use with third party programs to indicate the users desire to
       have entries added to their FDB if not already present (Not supported
       by THDPLUS). This is equivalent to "SET THDOPT=ADD".

/DC - Dupe Check
      Check files prior to processing to see if they have already been
      processed "according to the THDPRO.DUP file" which is created by
      selecting to create a dupe list in THDINSTL.EXE.

/CO - Convert Only

/KO - Keep Original

/LA - Log all
      Do not fail a virus infected file until all scanners have been run.

/NODESC - Do Not update descriptions.
                                                                                
/OV - OVerride the default limits for size and time. Use this to test
      files manually which exceed time and space limits configured
      internally to THDPRO.EXE

/RO - Treat the test file as Read-Only. Use for CD-ROM's which are not
      autodetected by THDPRO.EXE or for files where you wish them tested
      but not modified in any way.

/TOxxx# - Convert to "xxx" at level "#"                                         

    ...where "xxx" = one of the following
       ARJ - LHA - RAR - SQZ - UC2 - ZIP

    ...and "#" =  nothing or one of the following
       0 - 1 - 2 - 3 - 4 - 5 - 6

/SEC - Generate THDPRO.SEC file (Required when Secure Mode is chosen).
