** Enabling Scanning Features **
**********************************************************************
Several scanning features can be enabled through the use of an INF
configuration file. For NAV for Windows 95/NT version 4.x and later,
or NAV for OS/2, this configuration file should be called NAVEX15.INF
and should be placed in the directory where NAV is installed (i.e.,
C:\Program Files\Norton AntiVirus). For NAV for Netware version 4.x,
the file should be called NAVEX15.INF and should be placed in the
directory where NAV 4.x is installed (i.e., sys:system\navnlm). For
NAV for Windows 95/NT version 2.0, NAV 4.x for Windows 3.1/DOS,
NAVIEG 1.x, or NAVFW 1.x, the file should be named NAVEX.INF and
should be placed in the directory where NAV is installed (i.e., C:\NAV).
If this configuration file does not exist, create one in the appropriate
directory if you want to change the default settings.
To enable a scanning feature for a particular component, one or more
entries need to be added to the configuration file under the correct
section. For each platform there is a corresponding section that is used
in the INF file. Below is a table of section names and platforms.
Section Name Platform
------------ --------
NAVW32 Windows 95/98/NT
NAVAP Windows 95/98/NT Auto-Protect
NAVDX DOS
NAVNLM Netware
NAVWIN Windows 3.1
NAVOS2 OS/2
NAVAIX AIX
NAVSOL Solaris
Entries are case insensitive. Below is a description of possible
entries.
1. Files can be excluded from scans by the NAVEX engine. To exclude a
specific file from the NAVEX engine scan, add an entry with the full
path and file name. This is case insensitive. No wildcards are allowed.
To exclude multiple files, add a separate entry for each file. To exclude
a file, add an entry like the one below where <PATH> is the full path
and file name.
ExcludeFile = <PATH>
2. Files within a directory can be excluded from scans by the NAVEX engine.
To exclude all files within a directory, add an entry with the full
directory path. This is case insensitive. No wildcards are allowed. This
does not exclude files located in subdirectories of the specified
directory. To exclude multiple directories, add a separate entry for each
directory. To exclude a directory, add an entry like the one below where
<DIRECTORY> is the full path.
ExcludeDirectory = <DIRECTORY>
The following example of an INF configuration file excludes two files,
NOSCAN.EXE and BIGFILE.DOC, from NAVEX scans for the Windows 95/98/NT
scanner. It excludes the D:\PRIVATE directory from Windows 95/98/NT
Auto-Protect.
[NAVW32]
ExcludeFile = C:\PROGRAM FILES\NOSCAN.EXE
ExcludeFile = C:\TEMP\BIGFILE.DOC
[NAVAP]
ExcludeDirectory = D:\PRIVATE
