What is the immunization feature and what are the other permanent protection options?

Spybot – Search & Destroy offers the Immunization – a feature to allow you to immunize your computer against certain pieces of spyware.
It also allows you to use native browser settings to block cookies, malware installations,
bad websites and other threats via ActiveX.
SDHelper is an Internet Explorer plugin that adds a second layer for blocking threats.
While the Permanent Immunity blocks installers by their ActiveX ID,
this one blocks anything that should come through by different aspects.
