Situation:
When you visit specific Web pages, the entire page is not displayed. If you disable some features of Norton Internet Security or Norton Personal Firewall, the entire page is displayed.

Solution:
This problem happens when Norton Internet Security or Norton Personal Firewall has been configured to block scripts, ActiveX controls, Java applets, referral information, or advertisements.

ActiveX controls and Java applets can be blocked by customizing your security settings from the main interface. To find out whether this is the problem, read the section "Customize security settings."

All of these security features (scripts, ActiveX controls, Java applets, referral information, and advertisements) can be blocked by specific Web rules. These rules are located in the Advanced Options of the program. For scripts, ActiveX controls, Java applets, and referral information, see the "Web rules" section of this document.

For information about the blocking of advertisements, see the document How to create a rule to override default ad blocking.

Customize security settings
The blocking of Java applets and ActiveX controls can cause the problem. It may be necessary to change security settings to prevent them from being blocked.

Click an icon to either expand ( ) or collapse ( ) the section for the version of Norton Internet Security or Norton Personal Firewall you are using. (If you cannot expand a section, then read the document Cannot expand sections in a Symantec Knowledge Base document.)

Technical Information:
How referrer information blocks portions of Web pages
When you open a Web page that includes graphics, the Web server for that page may use the referrer information to display the graphics. This happens when those graphics are stored on a different Web server than the one you are visiting. In this situation, the first Web server sends a request to the graphics Web server to obtain the graphics. The request includes the referrer information. The referrer information enables the graphics Web server to send the graphics to the correct location.

When you block the referrer information, the graphics Web server cannot send the graphics to the correct location, and you do not see the graphics that your current Web server would normally display.

How Ad Blocking blocks portions of Web pages
The advertisements that Norton Internet Security and Norton Personal Firewall block are often parts of Web pages, rather than entire Web pages. Norton Internet Security and Norton Personal Firewall know which parts are advertisements because the advertisements use specific coding. Norton Internet Security and Norton Personal Firewall compare the coding on the Web page against the Norton Internet Security and Norton Personal Firewall default list of advertisement codes to determine whether a part of the Web page is an advertisement.

When a code on the Web page matches a code in the Norton Internet Security or Norton Personal Firewall list, Norton Internet Security and Norton Personal Firewall block that part of the Web page. To configure Norton Internet Security or Norton Personal Firewall to allow that part to be displayed for any specific Web page, see the document How to create a rule to override default ad blocking.
