- --------------------------------------------------------
- Blocking ads speeds up download time
- --------------------------------------------------------
- The ad blocking feature does not block all
- advertisements on the Internet, but it can speed up
- download time when websites contain 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
- --------------------------------------------------------
- Blocking ads prevents specific HTML strings from being
- downloaded to a Web browser. This can prevent other Web
- elements from appearing in the browser in addition to
- advertisements. It can also cause script errors on some
- pages. If you visit a site that does not download
- properly, try disabling the Ad Blocking feature.
-
- Visit the Symantec Online Support Knowledge Bases for
- information on using the event log to help you determine
- why a site is blocked. Visit http://www.symantec.com/techsupp/.
-
- --------------------------------------------------------
- Blocking ads blocks graphical advertisements
- --------------------------------------------------------
- The Norton Internet Security ad blocking feature blocks
- graphical advertisements and pictures. It is not
- effective against text-based or script-based
- advertisements.
-
- --------------------------------------------------------
- Blocking applications from accessing the Internet
- --------------------------------------------------------
- Norton Internet Security restricts applications from
- accessing the Internet. It does not prevent someone from
- running the application.
-
- When some programs cannot access the Internet, they may
- respond by crashing, freezing, or reporting problems
- with your Internet connection. The results depend on how
- the program was designed.
-
- --------------------------------------------------------
- Blocking cookies does not prevent cookie creation
- --------------------------------------------------------
- Blocking cookies does not prevent the cookie from being
- stored on your hard disk. It prevents your browser from
- sending the cookie when a Website requests it. Norton
- CleanSweep and other similar products contain features
- to remove cookies from your hard disk.
-
- --------------------------------------------------------
- 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 page errors, or
- display warnings about updating your browser.
-
- To block information about the type and version of
- browser you are using:
- 1. Open Norton Internet Security.
- 2. Click Options and click Advanced Options.
- 3. Under the Web tab, click the privacy tab and change
- the Browser (User-agent) settings.
-
- --------------------------------------------------------
- Blocking popup windows is limited
- --------------------------------------------------------
- The Block Script Popups Only feature blocks the most
- common methods Web sites use to open additional browser
- windows, but does not block all methods. Even with this
- feature turned on, you might find Web sites where pop-up
- windows are not blocked.
-
- Some Web sites, such as Microsoft's Windows Critical
- Update, will not operate correctly when you block script
- popup windows.
-
- --------------------------------------------------------
- Blocking scripts only blocks scripts on Web page
- --------------------------------------------------------
- The advanced feature to Block All JavaScript blocks any
- JavaScript embedded in Web pages. However, it does not
- block JavaScript found in form objects or in external
- script (.JS) files.
-
- Blocking JavaScript causes errors on Web pages that
- require JavaScript for proper display or navigation, and
- 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
- displays the name of the process as N/A. If you create a
- firewall rule for N/A programs, make sure the rule
- blocks or permits the connection for a specific port or
- address. If you create a rule to permit
- or block N/A programs for all ports or addresses,
- Norton Internet Security will use that rule for every
- program it cannot identify.
-
- --------------------------------------------------------
- Firewall alerts are cached
- --------------------------------------------------------
- Sometimes Internet-enabled applications send requests to
- several computers to contact your machine. If you are
- using the Firewall Rule Assistant, you could see several
- alerts. Multiple alerts are cached in Norton Internet
- Security. This can cause alerts to appear even if you
- close the original program that caused the alert.
- Specific examples include multiplayer Internet games
- like Unreal Tournament or Gamespy.
-
- --------------------------------------------------------
- Incompatibility with Regclean
- --------------------------------------------------------
- Running some versions of Microsoft's Regclean power toy
- can break Norton Internet Security so that it stops
- working properly. To fix this problem, reinstall Norton
- Internet Security, or undo the registry cleanup. The
- registry cleanup and repair functions in Norton
- Utilities and Norton CleanSweep do not cause this
- problem.
-
- --------------------------------------------------------
- Permitted sites can contain items from blocked sites
- --------------------------------------------------------
- When you specify a list of permitted Websites, content
- from all other Websites is blocked. If a site reference
- graphics or other items from other sites, these items
- are blocked even though they appear to be from the same
- Web site.
-
- These are some steps you can take to reduce these
- situations:
-
- - Use domain names instead of more specific Web site
- names. For example, permit the site example.com
- instead of images.example.com to allow the content
- from the example domain. This allows access to all the
- websites within that domain, including www.example.com,
- help.example.com, images.example.com or any other
- sites in that domain.
-
- - If you are viewing a permitted site and notice images
- that are blocked, open the Event Log and look at the
- information under the Restrictions tab. This shows the
- items that were blocked from the Web site you are
- viewing. Then add the blocked sites to the permitted
- list so the blocked images will appear.
-
- These steps are only useful if you are specifying which
- sites are permitted. If you use the Specify Blocked
- Sites option, everything that does not fall into a
- blocked category is permitted.
-
- --------------------------------------------------------
- Referring address blocking is for browser only
- --------------------------------------------------------
- Although Norton Internet Security blocks the information
- from your browser about the last Web address you
- visited, it cannot block this information when it is
- passed from a Web server. 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. This information does not come
- from your browser, and is not blocked by Norton Internet
- Security. These occurrences should not cause privacy or
- security concern.
-
- --------------------------------------------------------
- Restricted account users do not see prompts
- --------------------------------------------------------
- Norton Internet Security lets you enable, block, or
- prompt the user for various settings. However,
- restricted account users do not receive prompts. For
- restricted accounts, any item set to prompt the user is
- automatically blocked without warning.
-
- --------------------------------------------------------
- Showing animated .gif files after blocking them
- --------------------------------------------------------
- One of the advanced options lets you 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 animated .gif blocking, 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, but terminating http connections
- requires that you close your Web browser software.
-
- --------------------------------------------------------
- Web Site Blocking and Browser History
- --------------------------------------------------------
- Most web browsers keep pages in a hard drive cache to
- improve performance, and some browsers support "offline
- browsing", where they download entire web pages to your
- hard disk. If these pages are viewed or downloaded by
- one account, they may be viewable by another account who
- would normally have these pages blocked with Parental
- Control. Empty your web browser's cache to solve this
- problem.
-
- --------------------------------------------------------
- Web Browser Compatibility
- --------------------------------------------------------
- Some features of Norton Internet Security, such as
- the web-based subscription update, are designed for
- modern web browsers. If you do not have a version 4.0+
- browser from Microsoft or Netscape, you may not be able
- to use these features.
-
- --------------------------------------------------------
- Hiding your computer name from the Internet
- --------------------------------------------------------
- In its default configuration, Norton Internet Security
- and Norton Personal Firewall 2001 hides your computer
- name and share information from being seen over the
- Internet if you have Microsoft File & Print Sharing
- enabled. This is a change from version 2000.
-
- The ability to share the computer name is required for
- some cable modem implementations, but is not necessary
- for most systems. If you need to share this information
- in order to connect to your internet service provider,
- please review the "Compatibility with Cable Modems"
- document on the Start Menu / Programs / Norton Internet
- Security (or Norton Personal Firewall) / Product Support
- for information on how to add this.
