Installing New Virus Definitions Files
======================================
This document details the virus definitions update procedures for:
* Norton AntiVirus for Windows 95
* Norton AntiVirus 3.0
* Norton AntiVirus Network Manager
* Norton AntiVirus for NetWare 2.0
* Norton AntiVirus Scanner for Windows NT
* Installing Virus Definitions Files Manually
_____________________________________________________________________
TIP: Be sure to read the WHATSNEW.TXT for important information about
new viruses. The new macro virus that infects Microsoft Excel files
requires you to add .xl? to the Program File Extensions List. For
instructions, see WHATSNEW.TXT.
_____________________________________________________________________
Intelligent Updater
===================
As part of our continuing commitment to fight the spread of computer
viruses, Symantec has developed a new program called Intelligent
Updater to simplify virus definitions files updates. Intelligent
Updater locates Norton AntiVirus on your computer and installs new
virus definitions files automatically. All you have to do is run the
program then scan your disk with Norton AntiVirus. Later sections of
this document give step-by-step instructions for each
Norton AntiVirus version.
The Intelligent Updater program file is located on your Virus
Definitions Update disk. The program name, which changes from month
to month, uses the following form:
mmNAVyy.EXE, where mm is the month and yy is the year.
For example, 10NAV96.EXE is the virus definitions files update
for October, 1996.
Norton AntiVirus for Windows 95
===============================
____________________________________________________________________
Important Notice: If your version of Norton AntiVirus for Windows 95
(NAVW32.EXE) is dated earlier than December 1, 1995, you need to
upgrade your software before updating the virus definitions files.
Using older versions of Norton AntiVirus for Windows 95 will cause
false detections when the new virus definitions are installed. The
Norton AntiVirus for Windows 95 upgrade program updates
Norton AntiVirus to detect and eliminate a new class of viruses
called macro viruses. These viruses infect Microsoft Word document
and template files, and Microsoft Excel files.
To upgrade your Norton AntiVirus program, download the file named
NAV95PCH.EXE. Place the file in an empty folder and execute
NAV95PCH.EXE to extract its contents. Step-by-step instructions
are included in the READNOW.TXT file.
NAV95PCH.EXE is located where the monthly virus definitions files
updates are normally found. It is available for download from the
Symantec BBS, the Symantec FTP or Web sites, CompuServe, America
Online, or Microsoft Network. You can also call Customer Service
at (800) 441-7234 to order a disk set.
To update Norton AntiVirus for Windows 95 virus definitions files:
1. Change to the folder where you downloaded the Intelligent
Updater program (10NAV96.EXE).
2. Double-click on the file 10NAV96.EXE.

3. Start Norton AntiVirus and scan your drive.
This activates the new virus definitions.
4. Restart your computer so that Auto-Protect uses the new
definitions as well.
Norton AntiVirus 3.0
====================
_____________________________________________________________________
Important Notice: If your version of Norton AntiVirus 3.0
(NAV.EXE or NAVW.EXE) is dated earlier than February 23, 1996, you
need to upgrade your software before updating the virus definitions
files. Using older versions of Norton AntiVirus will cause false
detections when the new virus definitions are installed. The
Norton AntiVirus 3.0 upgrade program updates Norton AntiVirus to
detect and eliminate a new class of viruses called macro viruses.
These viruses infect Microsoft Word document and template
files, and Microsoft Excel files.
To upgrade your Norton AntiVirus program, download the file named
UPDATEME.EXE. Place the file in an empty directory and execute
UPDATEME.EXE to extract its contents. Step-by-step instructions

any text editor).

updates are normally found. It is available for download from the
