The Internet Explorer browser does not treat all sites the same. This program uses a variety of "zones" or categories, and applies different security levels to each zone. For example, Internet Explorer can block potentially dangerous content such as ActiveX or Java scripts on general websites, yet allow this type of content on sites that you know and trust. You can add URLs to the "Trusted Sites" list of Internet Explorer to "whitelist" those sites, indicating that they are safe and trusted.
Click the "Internet Explorer" icon on the Windows taskbar. If the taskbar is not visible, click the "Desktop" tile on the Start menu or press the "Windows- D" key combination to switch to the Windows desktop view.

Click "Close" and then "OK." The site is now trusted by Internet Explorer.
