********************************************************************** PowerPoint Scanning is now enabled by default and can be optionally disabled. However, you may want to verify that files with PowerPoint extensions will be scanned by making sure that your NAV options have both ".PPT" and ".POT" in the list of extensions to scan. To disable PowerPoint scanning in NAV for Windows 95/NT version 4.x or NAV for OS/2, a text file named NAVEX15.INF should be placed in the directory where NAV 4.x or NAV 5.x is installed (i.e., C:\Program Files\Norton AntiVirus). To disable PowerPoint scanning in NAV for Netware version 4.x, a text file named NAVEX15.INF should be placed in the directory where NAV 4.x is installed (i.e., sys:system\navnlm). To disable PowerPoint scanning in NAV for Windows 95/NT version 2.0, NAV 4.x for Windows 3.1/DOS, NAVIEG 1.x, or NAVFW 1.x a text file named NAVEX.INF should be placed in the directory where NAV is installed (i.e., C:\NAV). The contents of the text file, NAVEX15.INF or NAVEX.INF, determine which components of NAV have PowerPoint scanning disabled. To disable PowerPoint scanning for a particular component, use the following table to determine the lines to add to the text file. PowerPoint scanning can be disabled for more than one component if needed by adding the required lines for the desired components. +---------------------+--------------------------+--------------------+ |Windows 95/NT scanner|Windows 95/NT auto-protect|DOS scanner | +---------------------+--------------------------+--------------------+ |[NAVW32] |[NAVAP] |[NAVDX] | |PowerPointScanning=0 |PowerPointScanning=0 |PowerPointScanning=0| +---------------------+--------------------------+--------------------+ +----------------------+--------------------+--------------------+ |Windows 3.1 scanner/AP|Netware scanner |OS/2 scanner/AP | +----------------------+--------------------+--------------------+ |[NAVWIN] |[NAVNLM] |[NAVOS2] | |PowerPointScanning=0 |PowerPointScanning=0|PowerPointScanning=0| +----------------------+--------------------+--------------------+ To enable PowerPoint scanning for a component, delete the lines added for that component from the NAVEX15.INF or NAVEX.INF file. ********************************************************************** ** Additional Information ** ********************************************************************** SARC has equipped Norton AntiVirus with a new feature called "Infestation Mode." If a large number of new or unknown viruses is found on the system during a scan, Norton AntiVirus will automatically enable its highest level of detection. This gives users the most comprehensive protection in cases where a viral infestation may have been detected. If you would like to disable this feature, you can do so by following these instructions: 1. Create a text File called NAVEX15.INF in your Norton AntiVirus directory,e.g., C:\Program Files\Norton AntiVirus. If this file already exist go to step two. 2.
