  310. **    Enabling Scanning Features                            **
  311. **********************************************************************
  312.  
  313. Several scanning features can be enabled through the use of an INF 
  314. configuration file.  For NAV for Windows 95/NT version 4.x and later, 
  315. or NAV for OS/2, this configuration file should be called NAVEX15.INF
  316. and should be placed in the directory where NAV is installed (i.e.,
  317. C:\Program Files\Norton AntiVirus).  For NAV for Netware version 4.x,
  318. the file should be called NAVEX15.INF and should be placed in the 
  319. directory where NAV 4.x is installed (i.e., sys:system\navnlm). For
  320. NAV for Windows 95/NT version 2.0, NAV 4.x for Windows 3.1/DOS,
  321. NAVIEG 1.x, or NAVFW 1.x, the file should be named NAVEX.INF and
  322. should be placed in the directory where NAV is installed (i.e., C:\NAV).
  323. If this configuration file does not exist, create one in the appropriate
  324. directory if you want to change the default settings.
  325.  
  326. To enable a scanning feature for a particular component, one or more 
  327. entries need to be added to the configuration file under the correct
  328. section.  For each platform there is a corresponding section that is used 
  329. in the INF file.  Below is a table of section names and platforms.
  330.  
  331. Section Name    Platform
  332. ------------    --------
  333. NAVW32          Windows 95/98/NT
  334. NAVAP           Windows 95/98/NT Auto-Protect
  335. NAVDX           DOS
  336. NAVNLM          Netware
  337. NAVWIN          Windows 3.1
  338. NAVOS2          OS/2
  339. NAVAIX          AIX
  340. NAVSOL          Solaris
  341.  
  342. Entries are case insensitive.  Below is a description of possible 
  343. entries.
  344.  
  345. 1. Files can be excluded from scans by the NAVEX engine.  To exclude a
  346. specific file from the NAVEX engine scan, add an entry with the full
  347. path and file name.  This is case insensitive.  No wildcards are allowed.
  348. To exclude multiple files, add a separate entry for each file.  To exclude
  349. a file, add an entry like the one below where <PATH> is the full path
  350. and file name.
  351.         ExcludeFile = <PATH>
  352.  
  353. 2. Files within a directory can be excluded from scans by the NAVEX engine.
  354. To exclude all files within a directory, add an entry with the full 
  355. directory path.  This is case insensitive.  No wildcards are allowed.  This
  356. does not exclude files located in subdirectories of the specified 
  357. directory.  To exclude multiple directories, add a separate entry for each
  358. directory. To exclude a directory, add an entry like the one below where
  359. <DIRECTORY> is the full path.
  360.         ExcludeDirectory = <DIRECTORY>
  361.  
  362. The following example of an INF configuration file excludes two files, 
  363. NOSCAN.EXE and BIGFILE.DOC, from NAVEX scans for the Windows 95/98/NT 
  364. scanner.  It excludes the D:\PRIVATE directory from Windows 95/98/NT 
  365. Auto-Protect.
  366.  
  367. [NAVW32]
  368. ExcludeFile = C:\PROGRAM FILES\NOSCAN.EXE
  369. ExcludeFile = C:\TEMP\BIGFILE.DOC
  370.  
  371. [NAVAP]
  372. ExcludeDirectory = D:\PRIVATE
