                           ABOUT LIVEUPDATE
**********************************************************************
LiveUpdate is the Symantec technology that permits an installed 
Symantec product to connect to a Symantec server over the Internet to 
check for program and other updates such as virus definitions and URL 
lists.

When updates are available, LiveUpdate downloads them to your computer 
and installs them, keeping your Symantec software up to date. With
this latest release of LiveUpdate we now add digital signature 
verification to the update process so that you can be sure we only 
install content that has been authenticated.

Certain types of content may require a subscription and so LiveUpdate 
will only download subscription content if a valid subscription is 
found on your machine.

**********************************************************************
                              WHAT'S NEW?
**********************************************************************
1. Security. When LiveUpdate downloads the catalog of available 
updates it will now check for a Symantec digital certificate and only
proceed with the update process if the file was signed by Symantec. In
addition, the cryptographic signatures are verified for all updates 
that are downloaded before they are applied to the machine.

2. Windows XP compatibility. This version of LiveUpdate has been fully
tested on the Windows XP operating system. We have no known 
incompatibilities with this new OS at this time.

3. Improved logging. As with any application that uses the Internet,
LiveUpdate will sometimes fail due to the prevailing Internet 
conditions. In an effort to improve the troubleshooting process we 
have improved the logging feature in LiveUpdate. In addition, we now  
write critical security events to the NT Event Log.

**********************************************************************
                              PROXY SERVERS
**********************************************************************
Most Internet users don't need to configure their computers to use a 
proxy server, however some ISPs and companies require you to connect 
to the Internet through a proxy server. So, we've made it easier then 
ever via a 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 then choose either the second or third radio buttons.

The second radio button allows you to customize your proxy server 
settings and the third button tells LiveUpdate to use the same proxy 
server settings that you have setup for use with Internet Explorer.

* Note: LiveUpdate uses HTTP for file transfers by default, however it
will fail over to FTP if it is unable to communicate via HTTP.

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).  

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.

**********************************************************************
                         VERSION INFORMATION
**********************************************************************
To determine the exact version of LiveUpdate that you have installed 
on your machine, open Windows Explorer and locate the file luall.exe. 
This is usually located in the LiveUpdate client installation folder 
(\Program Files\Symantec\LiveUpdate). Right click on this file and 
select Properties. On the Version tab the File version information 
will be listed.

**********************************************************************
                           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. This will automatically download 
updates for all Symantec products, which use our One Button Update 
technology. You can also run LiveUpdate from the folder created under
the start menu by your Symantec product(s).

Note: Some product updates may only be retrieved by selecting the
LiveUpdate option from within that product.

**********************************************************************
                          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.

Updates to LiveUpdate are also posted to the URL below.
http://www.symantec.com/techsupp/files/lu/lu.html

**********************************************************************
                   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:

http://www.symantec.com/techsupp/files/lu/lu.html

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.  

To uninstall LiveUpdate:
1. From the Start menu, select Settings > Control Panel.
2. Double-click Add/Remove Programs.  
3. Select LiveUpdate from the list and then click Add/Remove.

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

**********************************************************************
		LIVEUPDATE CONFIGURATION & LOG FILES
**********************************************************************
LiveUpdate stores all of its configuration and logging information in 
the following files:

log.liveupdate			- Log file
product.catalog.liveupdate	- List of installed Symantec products
settings.liveupdate		- Configuration settings

LiveUpdate will also keep backup copies of these files by adding a 
number to the beginning of the filename. The higher the number the 
older the file.

These files are normally located in the 'Application Data' folder on 
your machine. The location of this folder is OS dependent, however for
Windows 9x machines it is usually in 
\windows\all users\application data\Symantec\liveupdate
and for new Windows NT/2K/XP systems it is sometimes located in
\Documents & Settings\all users\application data\Symantec\liveupdate

If you cannot find this folder its best to search for one of the
filenames noted above.

LiveUpdate does not remove its configuration or log files when you
uninstall.

**********************************************************************
                      USING AOL (America Online)
**********************************************************************
Symantec has documentation in our online knowledgebase that can assist 
you in using LiveUpdate with America Online.  Please go to the 
following URL to review this information:

http://service1.symantec.com/SUPPORT/sharedtech.nsf/docid/19982515512

An important issue in configuring LiveUpdate to work with AOL is to 
first make sure you are using a recent version of the AOL software.
Follow these steps to get LiveUpdate to work with an AOL connection.

Note: if you are using AOL to connect to the Internet via your modem, 
LiveUpdate requires that a TCP/IP connection be established prior to 
launching LiveUpdate. Symantec is not liable for any phone charges 
incurred when making this dial up connection.

1) Update to the latest release of LiveUpdate.  Normally, LiveUpdate 
will automatically update itself.  However, following the instructions 
in the section above titled "INSTALLING/UNINSTALLING LIVEUPDATE" will 
ensure that you have the most current version of LiveUpdate.

2) Click on the START button on your desktop, then select SETTINGS, 
and then CONTROL PANEL.  Then double click on the LiveUpdate icon. 

3) Next, click on the ISP tab.  SELECT the option to "The Internet 
options in the Control Panel". If you do this, LiveUpdate will 
automatically use your already opened Internet connection. Close the
control panel.

4) Sign on to your AOL account. The AOL software will dial your AOL 
access phone number and make the Internet connection.

5) Once connected, launch LiveUpdate from your Symantec software. The 
software will then detect your already opened AOL connection, and use 
it to download any available Symantec software updates that you 
require.

Don't forget to close your Internet connection when you have completed
your LiveUpdate session.

**********************************************************************
                       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 ISP tab
3) Select the "Customized settings for LiveUpdate" option
4) Within the "Use this Dial-Up Networking connection" section, 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". IBM Global Network 
should have provided both the Account and User ID to you.

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

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

**********************************************************************
                        TECHNICAL INFORMATION
**********************************************************************
LiveUpdate uses three possible methods, or transports, 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 canceled, 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
If LiveUpdate is unable connect via HTTP, it will attempt to use the 
older 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.  LAN (Local Area Network)
Corporate customers may wish to create their own internal LiveUpdate 
servers to ease bandwidth usage. More information about the LAN 
transport is available from within the LiveUpdate Administration 
Utility.

**********************************************************************
                            KNOWN ISSUES
**********************************************************************
1. Some Symantec products provided a link to the LiveUpdate control 
panel entry from the start menu. These links may not work any longer 
on some systems. If you wish to configure LiveUpdate you should open 
the control panel and double-click on the LiveUpdate icon.

2. Some corporations distribute a LAN transport option with 
LiveUpdate. If LiveUpdate finds this file in the same directory that 
it is being run from, it will search for a LAN entry in its settings 
file and use that transport instead on the FTP and HTTP transports.

3. Users of LiveUpdate with Norton Antivirus 2001 and later, should
note that the Automatic LiveUpdate component may be configured to 
check for virus definition updates in the background. Normally, 
LiveUpdate will only do this when it detects an open Internet 
connection, however some devices, dialup routers for example, can be 
configured to create an Internet connection when they detect this 
activity. Users should note that this could result in unexpected 
connection charges.

NOTE: ISDN on demand Internet access and Automatic LiveUpdate. ISDN
charges are generally higher than standard analog phone line charges 
so users of these systems are asked to pay particular attention to 
this issue.

4. Some "Ad Blocking" software products may deny LiveUpdate access to
the file servers from which it downloads updates. If you are using 
this type of software you should disable it if you notice problems 
downloading LiveUpdate packages. Once you have finished with 
LiveUpdate you can re-enable the "Ad Blocking" software.

5. If you use defragmentation software and you use the Automatic 
LiveUpdate feature, you should note that this may cause the 
defragmentation software to restart every time Automatic LiveUpdate 
checks for an Internet connection (usually every 5 minutes). If you 
notice this behavior while defragmenting your hard drive it is 
suggested that you pause the task scheduler until defragmentation has 
completed.

6. Some 'Zip' utilities may intercept the updates that are being 
downloaded by LiveUpdate and cause problems while LiveUpdate is 
trying to uncompress these files. For example, you may see the 
following error when using the ZipMagic utility from Mijenix: "Can Not 
Read The List of New Updates".

You can work around this problem by temporarily turning off the Zip 
Folders feature in ZipMagic. Other Zip utilities should provide a way
to temporarily disable themselves also.

For ZipMagic, to prevent the problem from occurring again, use the 
following steps to update ZipMagic's list of incompatible 
applications:

	a. Right click ZipMagic's "Zip" icon in the toolbar and choose 
	"Properties" from the menu.

	b. Click the "Zip Folders" tab on the left of the ZipMagic 
	window.

	c. Click the "Applications" tab on the bottom of the Zip 
	Folders	feature list.

	d. To the right of the list box, click the "Add..." button to 
	bring up the Add New Application dialog box.

	e. Click the "Browse..." button to find the LiveUpdate program 
	file.

	f. Click the "Look in" drop-down list and choose the drive 
	LiveUpdate is installed on (typically drive C).  Double click 
	the folders, "Program Files", then "Symantec", then 
	"LiveUpdate".  Then double-click the file "LuComServer.exe".

	g. In the "Add New Application" window, click the "Add" 
	button.

	i. Click the "Done" button.  (Be sure you've already clicked 
	"Add"!)

	h. In the ZipMagic window, click Ok to apply the change.
