                           ABOUT LIVEUPDATE
**********************************************************************

LiveUpdate is the Symantec technology that permits an installed
Symantec product to connect to a Symantec server automatically for
program and virus definitions updates.  The connection is made through
either a preset telephone number or an Internet site.  LiveUpdate can 
also be configured to use a local network server as bandwidth requires 
(for corporate customers).  To do this, download the LiveUpdate 
Administration Utility at:

ftp://ftp.symantec.com/public/english_us_canada/liveupdate/updates/luau.exe


**********************************************************************
                              WHAT'S NEW
**********************************************************************

LiveUpdate 1.5 has many new changes:

One Button Update:
LiveUpdate 1.5 now has the ability to retrieve and install updates for 
multiple Symantec products simultaneously.  Many Symantec products released 
after February 1999 contain this feature.

Download Resumption:
LiveUpdate can resume interrupted transfers transparently.  If you've 
ever had a download interrupted by call-waiting or internet problems, you'll
appreciate this new feature.  

Download resumption is available for both the HTTP and Modem transports.
It is not available for the FTP transport or for the LAN transport 
(corporate customers only).

Proxy Servers:
Most internet users don't need to configure their computers to use a proxy 
server, but we've made it easier then ever via a new Proxy tab in the
LiveUpdate Control Panel.

Note: If you do not know what a proxy server is, it may be best to set options
      using the Proxy tab only when instructed to do so by a network 
      administrator.

To configure LiveUpdate to use a proxy server, simply select the Proxy tab 
and put a checkmark in "Connect through a Proxy Server".  By default, 
LiveUpdate will use your Internet Explorer Proxy Settings (if available), 
but you can easily specify your own custom settings for both FTP and HTTP.

* Note: LiveUpdate now uses HTTP by default.  

If your proxy server requires authorization for outside access, you can also 
enter a Username and Password for either FTP or HTTP (or both) proxy access.  
Please note that this is different from the username and password you use to 
connect to your Internet Service Provider (if you use one).  

Certain networks are configured only to allow FTP to use a "passive 
connection".  If you have difficulty using the FTP transport, check the
box on the Internet tab of the LiveUpdate control panel labeled "Use Passive 
mode FTP transfers".

If you have any difficulty configuring your proxy settings, contact your 
network administrator for assistance.  Each network is different, so 
only they can help you with this step.


**********************************************************************
                           RUNNING LIVEUPDATE
**********************************************************************

Most Symantec products which use LiveUpdate offer a LiveUpdate button.  
In Norton SystemWorks, for example, you can run LiveUpdate from the 
SystemWorks Integrator.  You can also run LiveUpdate from the LiveUpdate 
Control Panel. This will automatically download updates for all Symantec 
products which use our One Button Update technology (discussed above).


**********************************************************************
                          UPDATING LIVEUPDATE
**********************************************************************

Sometimes even the update program needs an update.  LiveUpdate will
automatically check to see if there are any available updates to 
itself each time it is run.  It should update itself transparently 
(without any extra input), but in certain rare cases may require that
you run LiveUpdate one additional time to complete your session 
after it has finished its update.  If this is required, it will tell
you.


**********************************************************************
                   INSTALLING/UNINSTALLING LIVEUPDATE
**********************************************************************

All Symantec products which use LiveUpdate install it themselves, but
if you encounter a problem with LiveUpdate that you or Technical 
Support believe to be the result of an install problem or corrupted
files, you can reinstall easily.

To reinstall, locate LUSETUP.EXE on your system or download the latest 
version from the Internet at:

ftp://ftp.symantec.com/public/english_us_canada/liveupdate/updates/

Once the file is on your system, double click the icon.  You will be 
asked if you wish to install LiveUpdate.  Answer yes, and it will 
automatically reinstall.  Your previous settings will be saved,
and you will still be able to run LiveUpdate from any Symantec product
without further configuration.

If you wish to uninstall LiveUpdate, please note that you will no
longer be able to receive updates to your Symantec products.  Your
configuration information will also be removed so that when you reinstall,
you may need to re-configure custom proxy settings or connection info.

To uninstall LiveUpdate:

1. From the Start menu, select Settings > Control Panel.

2. Double-click Add/Remove Programs.  

3. Select LiveUpdate from the list, then click Add/Remove.

To reinstall LiveUpdate at any time, find the LUSETUP.EXE
at the above URL and simply double-click it.


**********************************************************************
                        TECHNICAL INFORMATION
**********************************************************************

LiveUpdate uses four possible methods for retrieving updates and 
installing them.

1.  HTTP

We now use HTTP to download files from the Internet.  This replaces
FTP as our primary method for the following reasons.

 a: With the advent of the World-Wide-Web, HTTP is more widely used
    than FTP. More Internet Service Providers and corporations
    are configured to allow unrestricted HTTP transfers than FTP.
    This reduces the likelihood that you will need to configure 
    LiveUpdate manually.

 b: Through switching to HTTP, LiveUpdate now offers Download
    Resumption via the Internet.  If a LiveUpdate transfer is
    interrupted because of a severed connection to the internet
    (due to line noise or call waiting, for example) or merely
    cancelled, it can be continued the next time LiveUpdate is run.

 c: HTTP is slightly faster than FTP.  Also, if the file that
    LiveUpdate uses to determine the availability of updates has
    not changed since the last time it was run, LiveUpdate can
    now detect it and avoid re-transferring it. This will make
    your LiveUpdate sessions faster than before.

2.  FTP

FTP is the backbone of file transfers on the Internet.  If LiveUpdate
is unable connect via HTTP, it will attempt to use the old FTP method
automatically.  FTP does not offer download resumption. Corporate
customers may need to configure LiveUpdate to use an FTP proxy or 
to use FTP in passive mode (as discussed above), but
the updates it downloads are identical to those retrieved via HTTP.

3.  Modem

For customers who do not have access to the Internet, we offer
Modem transport.  Using this, LiveUpdate can make a phone call to
a computer near you (depending on your location). Note that if the
call is outside your local dialing area, your long distance
telephone service carrier may charge you for the call.

If a modem download is cancelled or interrupted (by line noise or
call waiting), it will resume the transfer the next time LiveUpdate 
is run.  This feature is especially important in countries with 
unreliable phone service and should significantly reduce the amount 
of time spent downloading.

4.  LAN (Local Area Network)

Corporate customers may wish to create their own internal LiveUpdate
servers to ease bandwidth usage.  For more information on this,
download the LiveUpdate Administration tool referenced earlier in 
this document.

In addition to the previous three transports mentioned, corporate
customers may configure a network server to provide the updates
using a standard file copy operation.  This may be faster and easier
to configure than FTP or HTTP.  More information about the LAN
transport is available from within the LiveUpdate Administration
Utility.


**********************************************************************
                      USING AOL (America Online)
**********************************************************************

If you are attempting to update your Symantec product using LiveUpdate 
and you have AOL installed you should take note of the following: 
If you are connecting to the Internet via your modem, LiveUpdate requires
that a TCP/IP connection be established. If you have AOL installed, 
you need to first dial up to your local AOL access number and go 
on-line/login with your AOL account. You do not need to configure 
LiveUpdate settings in any way. Run LiveUpdate from the Control Panel 
Applet or from any of the Symantec Products that you have installed. 
Note that Symantec is not liable for any phone charges incurred when 
making this dial up connection.

**********************************************************************
                       USING IBM GLOBAL NETWORK
**********************************************************************

If you are already online with your IBM Global Network service you do
not need to follow these instructions. The following information 
only applies if:

1) You wish to use an IBM Global Network to connect to the Internet 
2) You are not on-line when a LiveUpdate session is started

If you are using the IBM Global Network Dial-Up Networking client to 
establish an Internet connection to enable LiveUpdate to connect
to the Symantec LiveUpdate servers, you are required to have the 
following settings:

1) From the Control Panel double-click on the LiveUpdate icon to open
   the LiveUpdate Settings Applet
2) Select the Internet tab
3) Enable "Connect to the Internet using a modem"
4) Within the "Use the Dial-Up Networking connection" select 'IBM Global 
   Network'
5) Within the "User Name" field enter first the "Account" followed by 
   either a period, "." or "\" and then the "User ID". 
   Both the IBM Global Network Account and User ID should have been 
   provided to you by IBM Global Network

                      i.e. Username: myaccount.myusername
                           Password: mypassword

6) In the "Password" field enter the password as provided to you by IBM 
   Global Network
