The Microsoft Internet Explorer Web browser feature can be expanded through the installation of "plug-in" programs called "ActiveX controls." ActiveX controls are usually configured to automatically download and install to computers when computers connect to a website, which is a convenience and also a security concern. Configure Internet Explorer with settings that enable downloading and running ActiveX controls before ActiveX control installation.
