You're welcome.
Unfortunately,I'm not sure why your Spybot is auto updating and immunizing.Your version shouldn't be.
The immunizing logfile doesn't look like it has anything in it useful as far as this is concerned,I'll skip that for now.
I'm not sure if your updates file will tell me what's happening,but that one might be worth a look.
Could you open Spybot-S&D Start Center,checkmark Advanced User Mode,click Update,then over to the left click Show Update log.Go to edit,select all,then rightclick,select Copy,then paste it here.
As for the updates,when you first click on Update,it does a status check,and the box comes up and tells you how many files are up-to-date.After that,you can click on the Update button to download any new updates.
