I want to thank all who replied and guided me.
I did everything as suggested and additional research and tweaking before ok-ing Win 10. It was not until the following morning I had everything ready.
The really great news is that Win 10 installed seamlessly … I had one 3 second flash of “no firewall” warning in Avast and it corrected itself without a reboot in seconds. Avast and MBAM are like best friends (LOL) and absolutely NO issues with Win 10 operating with both of them, or they with Win 10.
SMOOOTH!
It REALLY REALLY pays to do the checking, updating, tweaking before installing Win 10. Taking the time to make sure that Avast! version is updated and stable, and is not conflicting with anything else (like the MBAM) well before ok-ing the Win10 install prevents lots of pain after the fact.
Proactive beats Reactive EVERY TIME!
Win10 is pretty cool… still learning something new every day.
Thank you again to all who took the time to reply to my little thread!
