Question about operation of Spybot immunization and how to reverse/undo immunization

[krazykat1]

I have a couple of questions about the immunization process.
Is there a tutorial that explains what the immunization process does? I have WIN7 Pro 64 bit and install Spybot version 2.0.12.0 (free version). Spybot completed some of the immunization process. I believe the immunization has blocked some important websites that I use, because after the immunization I cannot access the sites. How can I COMPLETELY remove the immunizations that Spybot has done, so I can check if Spy bot is the source of the blocked websites? If I uninstall Spybot will the immunizations be removed? I looked at the hosts file and there are a very large number of entries placed by Spybot, it would be very hard to guess which ones to remove.
Getting access to the websites is critical, so any comments, suggestions would appreciated.
Thank you for your help,

There's info about immunization on this page:

No,I don't believe it does.
Spybot does ask if you'd like to undo changes rather than uninstalling,and there's a button to open Immunization,though.

To remove Immunization you can open Spybot-S&D Start Center,click Immunize,select Immunize everything when prompted,then click Undo Immunization.

Spybot version 2.0.12.0 looks like an older version.There was a 2.1/2.2 version of Spybot released after that,if you wanted to update your version.
