Intelligent Updater
=====================================================================
As part of SARC's 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 available in many on-line
areas as well as distributed on the monthly 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, 11NAV96A.EXE is the virus definitions files update
for November 5, 1996.
=====================================================================
Norton AntiVirus Program Upgrades
=====================================================================
If your version of Norton AntiVirus (NAV.EXE, NAVW.EXE or NAVW32.EXE)
is dated before June 1, 1996, you should update it with the latest
program updates available. As viruses continue to be discovered with
alarming regularity, the NAV virus definitions files have grown in
size to counter the latest threats. Applying the patches will ensure
that your installation will continue to accept the latest (and
largest) virus definitions files. Using older versions of Norton
AntiVirus can cause false detections when the new virus definitions
are installed.
Norton AntiVirus 3.10 Engine Update (UPDATEME.EXE)
--------------------------------------------------
To upgrade your Norton AntiVirus 3.0 program:
* Download the file called UPDATEME.EXE
* Place the file in an empty directory and execute the file
to extract its components.
* Enter: PATH; at the DOS prompt.
DonÆt forget the semicolon. This command temporarily disables
your path statement and will prevent corruption of NAV Network
Manager installations.
* Run UPDATE.EXE to create a set of install files.
To place these files on floppies and create a new installation
disk set, enter A:\ when it prompts for a location to EXTRACT the
files to.
* From DOS, run INSTALL.EXE.
* After applying this patch, you must also update your virus
definition set.
NAV for Windows 95 v1.0, 95.0b Large Volume Update (NAV95OB.EXE)
----------------------------------------------------------------
This latest patch also adds support for Microsoft Service Pack 2 (FAT
32/large volumes) and will be required to apply the December 1996
virus definitions set.
To upgrade your Norton AntiVirus for Windows 95 program:
* Download the file called NAV95OB.EXE
* Close (exit from) all open applications before running
NAV950B.EXE.
* Place the file in an empty folder and execute the file
to begin the installation process.
* After applying this patch, you must also update your virus
definition set.
If you need additional instructions, a FaxBack service is available
at (541) 984-2490. Request documents 4200 and 4221.
UPDATEME.EXE and NAV95OB.EXE are located where the monthly virus
definitions files update are normally found. They are available for
download from the Symantec BBS, the Symantec FTP or Web site,
CompuServe, America Online, or Microsoft Network. You can also call
Customer Service at (800) 441-7234 to order a disk set.
