--------------------------------------------------------
Blocking ads speeds up download time
--------------------------------------------------------
Ad Blocking does not block all advertisements on the 
Internet, but it can reduce the amount of time it takes 
your browser to display Web sites containing several 
ads. For information on blocking ads not blocked by 
Norton Internet Security see the User's Guide or Help.

--------------------------------------------------------
Blocking ads can block other Web elements
--------------------------------------------------------
Norton Internet Security blocks ads by preventing your
Web browser from displaying specific HTML strings. This 
may also prevent your browser from correctly displaying 
some page elements and cause script errors on some 
pages. If you visit a site that does not display 
properly, try disabling Ad Blocking and reloading the 
page.

The Symantec KnowledgeBase contains information on how
to use the Log Viewer to determine why a site is 
blocked. Visit http://www.symantec.com/techsupp/, or 
select the Support item in the Help menu.

--------------------------------------------------------
Blocking ads blocks graphical advertisements
--------------------------------------------------------
The Norton Internet Security Ad Blocking feature blocks 
graphical advertisements, Flash animations, and popup
and pop-under ads. It is not effective against text-
based or script-based advertisements.

--------------------------------------------------------
Blocking programs from accessing the Internet
--------------------------------------------------------
Norton Internet Security restricts programs from 
accessing the Internet, but it cannot prevent users from
running restricted programs. If a user attempts to run
a restricted program, the program may crash, freeze, or
report problems. The results depend on how the program 
was designed.

--------------------------------------------------------
Blocking browser type and version is off by default
--------------------------------------------------------
By default, Norton Internet Security does not block 
information about the type of browser you are using 
because many Web sites depend on this information to 
display Web pages tailored for specific browsers.

Blocking this information can cause Web pages to 
display incorrectly or trigger warnings that you need 
to update your browser.

To block information about the type and version of
browser you are using:
1. Open Norton Internet Security.
2. Click Options > Norton Internet Security.
3. Click the Web Content tab.
4. On the Global Settings tab, in the Information about 
   your Browser section, click Block.
5. Click OK.

--------------------------------------------------------
Blocking popup windows is limited
--------------------------------------------------------
The Popup Blocking feature blocks the most common 
methods that Web sites use to open additional browser
windows, but it does not block all methods. Even with 
this feature turned on, you might find Web sites where 
popup windows are not blocked.

Some Web sites, including Microsoft's Windows Critical
Update, will not operate correctly when you block 
script popup windows.

--------------------------------------------------------
Blocking scripts only blocks scripts on Web page
--------------------------------------------------------
You can choose to block JavaScripts using the Global
Settings tab of the Web Content options. This blocks 
any JavaScripts embedded in Web pages, but it does not
block JavaScripts that are in form objects or in 
external script (.JS) files.

Blocking JavaScript will cause problems with Web sites 
that use JavaScript for display or navigation. This 
feature should only be used by advanced users.

--------------------------------------------------------
Creating firewall rules for N/A programs
--------------------------------------------------------
If Norton Internet Security cannot identify a program 
or process that is attempting to access the Internet, 
it identifies the program or process as N/A. If you 
create a firewall rule for N/A programs, you should 
specify a particular port or address. Permitting or 
blocking N/A programs for all ports and addresses may 
negativelyimpact your protection because Norton 
Internet Security will apply that rule to every program 
it cannot identify.

--------------------------------------------------------
Firewall alerts are cached
--------------------------------------------------------
Sometimes Internet-enabled programs send requests to
several computers to contact your machine. As a result,
you may receive multiple alerts. To ensure that you are
informed about all connection attempts, Norton Internet
Security caches firewall alerts. As a result, you may 
continue to receive alerts about a program even after 
you have closed it.

Specific examples include multiplayer Internet games
like Unreal Tournament or Gamespy.

--------------------------------------------------------
Permitted sites can contain items from blocked sites
--------------------------------------------------------
When you specify a list of permitted Web sites, content
from all other Web sites is blocked. If a site uses
graphics or other items from other sites, these items
will be blocked even though they appear to be from the
site you are viewing.

To avoid this problem:

- Use domain names instead of more specific Web site
  names. If you permit www.example.com, you will only
  be able to view content from that Web site. If you 
  permit example.com, users will be able to view all 
  content from the example domain, including 
  www.example.com, help.example.com, img.example.com 
  or any other sites in that domain.
 
- If you are viewing a permitted site and notice 
  blocked images, open the Log Viewer and select the 
  Restrictions tab. This lets you see the site that 
  contains the blocked items. You can then add the site 
  containing the blocked items to the list of permitted 
  Web sites.
 
These steps only apply if you specify permitted sites. 
If you specify blocked sites, users can view all sites 
that are not blocked.

--------------------------------------------------------
Referring address blocking is for browser only
--------------------------------------------------------
Norton Internet Security prevents your browser from 
providing information about the last Web site you 
visited to other Web sites. It is still possible for a 
Web server to provide this information. For example, if 
you visit a site that refers you to another site on the 
same Web server, the Web server might transfer the 
referring information internally. Since this 
information does not come from your browser, Norton 
Internet Security cannot block the information. In most 
cases, these occurrences should not cause privacy or 
security concern.

--------------------------------------------------------
Restricted account users do not see prompts
--------------------------------------------------------
Norton Internet Security lets you choose to 
automatically allow, block, or notify the user when 
certain security events occur. Child users do not 
receive these alerts. Any item set to prompt the user 
is automatically blocked when a Child user is logged on 
to Norton Internet Security.

--------------------------------------------------------
Showing animated .gif files after blocking them
--------------------------------------------------------
Norton Internet Security can prevent animated .gif 
files from repeating their animation. This feature
modifies incoming .gif files to prevent them from
animating. To show the animation of a modified .gif file
again, turn off the Block animated images, clear your
browser's cache and revisit the Web site where you found
the file so you can download it again.

--------------------------------------------------------
Terminating http connections
--------------------------------------------------------
Norton Internet Security lets you terminate most types 
of network connections from the Detailed Statistics 
window. To terminate http (Web) connections, you must
close your Web browser.

--------------------------------------------------------
Web site blocking and browser cache
--------------------------------------------------------
Most Web browsers improve performance by saving recently
visited pages in pages in a hard disk cache. Some
browsers also support offline browsing, which lets you 
download Web pages to your hard disk for later viewing. 
If an Adult user views Web pages that would normally 
be blocked by Parental Control, other users on this 
computer may be able to view the cached version of these
Web pages. To ensure that Child and Teenager accounts
do not view inappropriate cached content, empty your
Web browser's cache before logging off your Norton 
Internet Security account.

--------------------------------------------------------
Hiding your computer name from the Internet
--------------------------------------------------------
By default Norton Internet Security hides your computer 
name and share information when you use Microsoft File 
and Print Sharing.

Some cable Internet Service Providers require customers
to share their computer names. If you need to share
your computer name to connect using your cable modem,
consult the Troubleshooting section of the User's Guide
or Help.

--------------------------------------------------------
Attacks and AutoBlock
--------------------------------------------------------
When Intrusion Detection identifies an intrusion 
attempt or port scan, it places the suspected attacker's
IP address in the AutoBlock list for 30 minutes. Norton
Internet Security automatically blocks all communication
with computers on the AutoBlock list.

If you are repeatedly attacked from a specific IP 
address, you can add that address to your Restricted 
Zone. Computers in the Restricted Zone cannot 
communicate with your computer at all.

--------------------------------------------------------
AutoBlock and legitimate connection attempts
--------------------------------------------------------
In some cases, Norton Internet Security may recognize 
normal activity as an attack. For example, some Internet
Service Providers run regular port scans of their 
customers' computers. Online security tests like 
Symantec Security Check (www.symantec.com/securitycheck/) 
may also be identified as attackers. 

If AutoBlock is incorrectly blocking a computer, you can
create an Exclusion for that computer. 
To exclude specific computers from AutoBlock

1. Open Norton Internet Security.
2. Double-click Intrusion Detection.
3. Click IP Address.
4. Do one of the following:
     * Select a blocked IP address in the Currently 
       blocked list and click Exclude.
     * Click Add and type in the computer’s name, 
       IP address, network identification, or a range 
       of IP addresses containing the computer you want 
       to exclude.
5. When you are done excluding IP addresses, click OK.

NOTE: Adding a computer to the Exclusion List does not
permit this computer to access your computer. This 
procedure simply prevents the computer from being added
to the AutoBlock list. All firewall security remains in 
place.

--------------------------------------------------------
Alerting while using DirectX and OpenGL
--------------------------------------------------------
If you are playing a game or using a program that 
takes full control of your screen and uses DirectX or
OpenGL to display 3D accelerated graphics, an alert for
network access may not appear properly or may appear to
lock up your machine. To avoid this, run Program Scan
and create the appropriate rules for all your games.

--------------------------------------------------------
Windows XP delayed startup on a network
--------------------------------------------------------
In some network environments, Windows XP may delay the 
startup of the Workstation service (and thus delay other 
program's startup) for up to a minute when Norton 
Internet Security is installed. This is because the 
Workstation service is trying to access the Bootps port 
before the firewall rule permitting this access has
loaded.

One soloution to this problem is to start Norton 
Internet Security manually. 

To block information about the type and version of
browser you are using:
1. Open Norton Internet Security.
2. Click Options > Norton Internet Security.
3. Click the Web Content tab.
4. In the Start Norton Internet Security section, select
   Manual.
5. Click OK.

To change your startup settings, click Options > Norton 
Internet Security, then select Manual.

--------------------------------------------------------
Limited accounts in Windows XP or Windows 2000
--------------------------------------------------------
Windows XP limited accounts or Windows 2000 Guest 
accounts usually have restricted access to the file 
system and registry. For this reason, people using these
types of accounts will not be able to change most of the
product settings.

People using limited or Guest accounts should not be 
given Supervisor access or allowed to make changes to
Norton Internet Security settings.

--------------------------------------------------------
Interaction with the Windows XP firewall
--------------------------------------------------------
Windows XP has a basic built-in firewall which is
superseded by Norton Internet Security. Running both 
firewalls simultaneously may cause problems with some
communications, including FTP. Symantec recommends 
disabling the Windows XP firewall before installing
Norton Internet Security.

--------------------------------------------------------
Supported instant messenger clients
--------------------------------------------------------
Privacy Control can protect private information in the 
following instant messenger programs:

 - MSN Messenger 3.6
 - AOL Instant Messenger 4.7

Privacy Control may also work with other instant
messenger programs that use http to communicate. 
To see if Privacy Control works with an instant 
messenger program, type a test item in the Private 
Information list, then use the instant messenger to 
send the protected information to someone.

--------------------------------------------------------
EarthLink setup and NetBIOS
--------------------------------------------------------
Some versions of the EarthLink setup program require 
access to NetBIOS ports. This may cause the EarthLink 
setup program to freeze if you have Norton Internet 
Security installed. If this occurs, either temporarily 
disable Norton Internet Security while installing 
EarthLink or deactivate the default block rules for 
NetBIOS and Windows File Sharing. For information on 
changing firewall rules by Norton Internet Security 
see the User's Guide or Help.

--------------------------------------------------------
Crash while using NetMeeting under Windows 2000
--------------------------------------------------------
Crashes while using NetMeeting on Windows 2000 may be 
related to a bug that Microsoft fixed with Windows 2000
Service Pack 2. Use Windows Update to update your 
operating system to Service Pack 2 or later for Windows 
2000.
