Norton Internet Security and how it effects downloading.
Norton Internet Security causes breaks in the web design of many sites. As you can see below, it blocks ActiveX, Java etc.... You will need to configure your Norton application for surfing sites that use the latest technology to bring you an excellent experience. From the Symantec Support Site: Cannot see all of a Web page when Norton Internet Security or Norton Personal Firewall is installed Situation: To customize security settings for Norton Internet Security or Norton Personal Firewall 2003/2004 To determine whether Web rules are blocking the page in Norton Internet Security or Norton Personal Firewall 2003/2004 How referrer information blocks portions of Web pages How Ad Blocking blocks portions of Web pages
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.
If either or both are set to block, lower the security level.
For example, www.test.com may be the Web site that contains the page www.test.com/samples/sample1.html.
An entry is added to the list for that Web site. If the Web site was already listed, it is not added again.
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.
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.
