Marking an ActiveX object safe for scripting

I recently ran a cross a problem where I had to create a COM component for use in Internet Exploder. In order to mark component safe for scripting you need to add the following to your Python class.

_reg_catids_ = ["{7DD95801-9882-11CF-9FA9-00AA006C42C4}"]

Now the class won't cause Internet Exporer to prompt for permission to load the component. I wonder why there is such a spyware problem? :0
