The Trusted Sites zone contains websites that you trust as safe. For example, trusted sites may include an organization's intranet or websites that belong to well-known companies. When you add a website to the Trusted Sites zone, you believe that files you download or that you run from the website will not damage your computer or data. By default, there are no websites that are assigned to the Trusted Sites zone, and the security level is set to Low.
