I apologize for frustration this may cause. I decided that rather than trying again, and perhaps stumbling onto the answer of key combination to do the dump, and then sending my RAM contents that I don’t really feel comfortable with sending, I tried a reinstall. The reinstall didn’t really go well, and I think I’ve just spent way too much time on this for now.

I really like Avast on my desktops and will continue with it there, but have for now returned to what was working well for me with this laptop. I do appreciate all the help, and hope you can understand my decision to move on for now.
