  399. **  Enabling Scanning Features                                      **
  400. **********************************************************************
  401.  
  402. Several scanning features can be enabled through the use of an INF 
  403. configuration file.  For NAV for Windows 95/NT version 4.x and later, 
  404. or NAV for OS/2, this configuration file should be called NAVEX15.INF
  405. and should be placed in the directory where NAV is installed (i.e.,
  406. C:\Program Files\Norton AntiVirus).  For NAV for Netware version 4.x,
  407. the file should be called NAVEX15.INF and should be placed in the 
  408. directory where NAV 4.x is installed (i.e., sys:system\navnlm). For
  409. NAV for Windows 95/NT version 2.0, NAV 4.x for Windows 3.1/DOS,
  410. NAVIEG 1.x, or NAVFW 1.x, the file should be named NAVEX.INF and
  411. should be placed in the directory where NAV is installed (i.e., C:\NAV).
  412. If this configuration file does not exist, create one in the appropriate
  413. directory if you want to change the default settings.
  414.  
  415. To enable a scanning feature for a particular component, one or more 
  416. entries need to be added to the configuration file under the correct
  417. section.  For each platform there is a corresponding section that is used 
  418. in the INF file.  Below is a table of section names and platforms.
  419.  
  420. Section Name    Platform
  421. ------------    --------
  422. NAVW32          Windows 95/98/NT
  423. NAVAP           Windows 95/98/NT Auto-Protect
  424. NAVDX           DOS
  425. NAVNLM          Netware
  426. NAVWIN          Windows 3.1
  427. NAVOS2          OS/2
  428. NAVAIX          AIX
  429. NAVSOL          Solaris
  430.  
  431. Entries are case insensitive.  Below is a description of possible 
  432. entries.
  433.  
  434. 1. Files can be excluded from scans by the NAVEX engine.  To exclude a
  435. specific file from the NAVEX engine scan, add an entry with the full
  436. path and file name.  This is case insensitive.  No wildcards are allowed.
  437. To exclude multiple files, add a separate entry for each file.  To exclude
  438. a file, add an entry like the one below where <PATH> is the full path
  439. and file name.
  440.         ExcludeFile = <PATH>
  441.  
  442. 2. Files within a directory can be excluded from scans by the NAVEX engine.
  443. To exclude all files within a directory, add an entry with the full 
  444. directory path.  This is case insensitive.  No wildcards are allowed.  This
  445. does not exclude files located in subdirectories of the specified 
  446. directory.  To exclude multiple directories, add a separate entry for each
  447. directory. To exclude a directory, add an entry like the one below where
  448. <DIRECTORY> is the full path.
  449.         ExcludeDirectory = <DIRECTORY>
  450.  
  451. The following example of an INF configuration file excludes two files, 
  452. NOSCAN.EXE and BIGFILE.DOC, from NAVEX scans for the Windows 95/98/NT 
  453. scanner.  It excludes the D:\PRIVATE directory from Windows 95/98/NT 
  454. Auto-Protect.
  455.  
  456. [NAVW32]
  457. ExcludeFile = C:\PROGRAM FILES\NOSCAN.EXE
  458. ExcludeFile = C:\TEMP\BIGFILE.DOC
  459.  
  460. [NAVAP]
  461. ExcludeDirectory = D:\PRIVATE
