SUMMARY
Digital Code Signing is a standard used to help ensure that content and files you download from the Internet have come from trusted sources and have not been altered since their creation. This also provides additional protection against computer viruses.



MORE INFORMATION
Digital Code Signing can be used for downloadable files and ActiveX Web page content.

When a file or an ActiveX page is downloaded, a check is performed to determine if the file or content was signed by the publisher and whether or not the certificate used to sign the code is valid. You are prompted to continue downloading the file based on the information that is displayed.

Internet Explorer 4.0/5
Internet Explorer 4.0/5 has four security settings:   High     Warns you if the file or contents fail to pass the security check, and does not accept the contents or file. You are not given the option to accept the incoming content.

Medium  Provides warnings about possible violations and allows you to choose whether to accept or reject the incoming file or           content.

None    You are not warned of possible security violations.

Custom  Security settings are based on settings you choose.

With Internet Explorer 4.0/4.01 you can also assign Web sites to different security zones.

For information about security zones, in Internet Explorer click Contents And Index on the Help menu, click the Index tab, type security, and then double-click the "What are security zones" topic.

To access the security setting, follow these steps:
 * 1) Start Internet Explorer, and then click Internet Options on the View menu.
 * 2) Click the Security tab.
 * 3) Click the security method you want to use.
