1) Installing the Windows-based File System Change notifier
-----------------------------------------------------------
To overcome the problem with Windows' 32-bit file access, we have
implemented a true Windows-based File System Change notifier module.

To install the TBAV VxD driver, just must either use the accompanying
setup program, or incorporate the changes by hand. You cannot use the
automatic update feature to install the TBAV VxD driver!

To install the TBAV VxD driver manually, you should first make sure
that all files belonging to TBAV for Windows V6.38 are present in the
TBAV directory. To install the TBAV VxD driver you must edit the
SYSTEM.INI file that resides in your Windows directory.

In the SYSTEM.INI file, you should add the following line in the
[386Enh] section:

        device=<full path of TBAV directory>\TBAVWIN.386

For example, suppose you have installed TBAV on your C: drive, in the
directory C:\TBAV. Then, the [386Enh] section of your SYSTEM.INI file
should look like te following:

        [386Enh]
        ...
        device=C:\TBAV\TBAVWIN.386
        ...

The lines with the three dots represent the existing entries in the
[386Enh] section of your SYSTEM.INI file.


2) Known problems with the Windows-based File System Change notifier
--------------------------------------------------------------------
The TBAV VxD driver that ships with TBAV-for-Windows V6.38 has one
known problem:

   Using the VxD driver in a DOS box with the 'Exclusive Execution' bit
   set will result in unpredictable behaviour. For each PIF file, you
   can set the 'Exclusive Execution' bit using the PIF Editor. This means
   that once you run a PIF file with this bit set, all Windows activity
   is suspended until you quit the program or minimize the program.
   Not only the VxD driver won't work, but the execution of other programs
   such as Print Manager, a Clock program etc. will be halted too.
   We recommend you *not* to set the 'Exclusive Execution' bit in any
   PIF file that you use.

3) Using the security options of TBAV-for-Windows
-------------------------------------------------
With the security options of TBAV-for-Windows you can disable some
of TBAV-for-Windows' features, for example using TbSetup, saving scan
options etc. By default, all features are enabled. If you want to change
the security settings you should use the "Security options" item in the
"Options" menu. Make sure to change the password first by clicking
the 'Password' button. You will be asked to enter your old password.
By default, this password is empty, so you should just press 'Enter'.
Then you can proceed with typing your new password and, once you're
back in the "Security Options" dialog, you can alter the security
settings.

4) Making special installation sets
-----------------------------------
By changing some options in the SETUP.INF you can alter the default 
settings from the Windows SETUP dialogs.
The default settings are put in the [Defaults] section in the SETUP.INF.
Following is a list of settings which defaults can be altered.

  DestinationPath      = C:\TBAV
  Installation         = 0  ; 0 = First-time, express installation
                            ; 1 = First-time, custom installation
                            ; 2 = Update installation

The following options only hold for First-time, express installation
Per default 0 = No, and 1 = Yes on the given command.

  AddTbStartStatement  = 1  ; Add 'Call C:\TBAV\TBStart.Bat' in Autoexec.bat ?
  AddPathStatement     = 1  ; Add 'Path=C:\TBAV' in Autoexec.bat ?
  AddTbScanX           = 1  ; Add 'TbScanX' in Autoexec.bat ?
  AddTbCheck           = 1  ; Add 'TbCheck' in Autoexec.bat ?
  AddTbMem             = 0  ; Add 'TbMem' in Autoexec.bat ?
  AddTbFile            = 0  ; Add 'TbFile' in Autoexec.bat ?
  AddTbScanOnce        = 1  ; Add 'TbScanOnce' in Autoexec.bat ?
  AddProgManGroup      = 1  ; Create Program Manager group in MS-Windows ?
  AddLoadIsStatement   = 1  ; Add 'Load=' statement in WIN.INI
  UseTbLoad            = 1  ; Use auto-update feature ?
  CreateDriveATarget   = 1  ; Create target file to scan drive A: ?
  CreateDriveBTarget   = 1  ; Create target file to scan drive B: ?
  CreateLocalTarget    = 1  ; Create target file to scan local drives ?
  CreateNetworkTarget  = 1  ; Create target file to scan remote drives ?
  CreateCDRomTarget    = 1  ; Create target file to scan CD-Rom drive ?
  CreateFullScanTarget = 1  ; Create target file to scan all drives ?
  PromptForDirectory   = 1  ; Ask for non-existent directories to be created ?
  DisableStopButton    = 0  ; Disable Stop button while installing
