The three main Internet Explorer protection features of Spywareblaster are....ActiveX CLSID's, Cookies and Restricted Sites. When you enable protection for any of those 3 features....you are in effect merging a .reg file into the proper Internet Explorer location of the registry for the protection selected.

Internet Explorer Protection:

• ActiveX protection sets a kill-bit to prevent the installation of ActiveX-based spyware / potentially unwanted software.
