I did a few site searches for this and browsed through the FAQs for Defense+ / Sandbox Help but I couldn't find a match.
There's a lot going on here so, if I missed a relevant thread please point me to it.
I'm finding that every time I turn on my PC, Defense+ is disabled. I've had it set on "Paranoid" and it's on when I shut down but disabled when I start back up.
Thanks in advance for any feedback.
