Thanx for the research. I'm not sure I really understand what this means. I can choose from different back up points, but each one trows me back on other improvements I made. That's basically a concern of remembering everything I changed, and guess I can handle that. But what would be a good date? Or would it help to throw away these particular services, and reinstall them? What part of my set-up is 'infected', or is that not an accurate way of looking at it?
