Bitdefender Quickscan Tools Cant Remove

Hi all,


By following this guide:


http://www.ehow.com/how_8328427_uninstall-...an-activex.html


I remove qsax-leading files from "C:\WINDOWS\Downloaded Program Files".


After i restart the IE9.0, I launch Tools -> Manage Add-ons -> Show all add-ons.


The bitdefender ActiveX is still here, it allowed to on/off the plugin.


May i know how to clean remove of Quickscan ActiveX.


Thank you very much.
