Hi Tech,
That is already done for you, my friend, from aprox. 237 vulnerable browser-plugins that were found up last year, 210 were INSIDE ActiveX controls, making this to the most dangerous browser plug-in to-day. Early this May Errata Security launched this free tool to block malicious ActiveX controls. Recently version 1.5 of AxBan, having an auto-update feature that downloads a list of the latest malicious ActiveX controls at start-up. There is also a possibility to cut and paste and additional information is also available. The tool is 64KB large. So it only attacks the baddies, and those that are not yet patched by MS.
Active-X was a misconception from the start, and why won't MS admit this fact,
