  431. **    Enabling/Disabling PowerPoint Scanning                            **
  432. **********************************************************************
  433. PowerPoint Scanning is now enabled by default and can be optionally
  434. disabled.  However, you may want to verify that files with
  435. PowerPoint extensions will be scanned by making sure that your
  436. NAV options have both ".PPT" and ".POT" in the list of extensions
  437. to scan.
  438.  
  439. To disable PowerPoint scanning in NAV for Windows 95/NT
  440. version 4.x or NAV for OS/2, a text file named NAVEX15.INF should
  441. be placed in the directory where NAV 4.x or NAV 5.x is installed
  442. (i.e., C:\Program Files\Norton AntiVirus).
  443.  
  444. To disable PowerPoint scanning in NAV for Netware version 4.x, a text
  445. file named NAVEX15.INF should be placed in the directory where NAV
  446. 4.x is installed (i.e., sys:system\navnlm).
  447.  
  448. To disable PowerPoint scanning in NAV for Windows 95/NT version 2.0,
  449. NAV 4.x for Windows 3.1/DOS, NAVIEG 1.x, or NAVFW 1.x a text file
  450. named NAVEX.INF should be placed in the directory where NAV is
  451. installed (i.e., C:\NAV).
  452.  
  453. The contents of the text file, NAVEX15.INF or NAVEX.INF, determine
  454. which components of NAV have PowerPoint scanning disabled.
  455.  
  456. To disable PowerPoint scanning for a particular component, use the
  457. following table to determine the lines to add to the text file.
  458. PowerPoint scanning can be disabled for more than one component if
  459. needed by adding the required lines for the desired components.

  481. SARC has equipped Norton AntiVirus with a new feature called
  482. "Infestation Mode."  If a large number of new or unknown viruses
  483. is found on the system during a scan, Norton AntiVirus will
  484. automatically enable its highest level of detection.  This gives
  485. users the most comprehensive protection in cases where a viral
  486. infestation may have been detected.  If you would like to disable
  487. this feature, you can do so by following these instructions:
  488.  
  489. 1. Create a text File called NAVEX15.INF in your Norton AntiVirus
  490.    directory,e.g., C:\Program Files\Norton AntiVirus. If this file
  491.    already exist go to step two.
  492.  
  493. 2. Place the following lines in this File on the left-hand margin:
  494.  
  495. [NAVW32]
  496. infestmode=0
  497.  
  498. [NAVDX]
  499. infestmode=0
  500.  
  501. 3. Save the File.
