DTBI113-IE11 - The Download unsigned ActiveX controls property must be disallowed (Restricted Sites zone).

Information

Unsigned code is potentially harmful, especially when coming from an untrusted zone. ActiveX controls can contain potentially malicious code and must only be allowed to be downloaded from trusted sites. They must also be digitally signed.

Solution

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Restricted Sites Zone -> 'Download unsigned ActiveX controls' to 'Enabled', and select 'Disable' from the drop-down box.
