How can I secure my internet by activex killbits wiki?

"Kill bit" is a security feature in web browsers based on the Microsoft Trident engine (such as Internet Explorer) and other containers of ActiveX kill bit respect (such as Microsoft Office). A kill bit indicates an ActiveX control container, never use a specific piece of ActiveX software, either third or Microsoft, as evidenced by the class identifier (CLSID).

The main purpose of a kill bit is to close security holes. If a vendor discovers that there is a flaw in a specific version of an ActiveX control, which may ask Microsoft to put a "kill bit" for this. Normally kill bit updates are implemented in Microsoft Windows operating systems through Windows Update.

Implementation
A flag in the Windows registry identifies a CLSID as unsafe. The CLSID acts as a software serial number in question - a GUID that must exist for each piece of software that acts as an ActiveX control. If a container is that ActiveX CLSID bit of a closing entry matches the CLSID of the software, the software prevents the execution of ActiveX container. If a provider wants to release an updated version after release with a different CLSID.
The application host HTML Internet Explorer also respects the kill bit for the treatment of the OBJECT tag in HTML, but not in the treatment of scripts in HTML.
