I temporarily uninstalled MBAM because my upgrade from Win 8.1 to win 10 was failing with a prompt that I should disable antivirus software.
OK, I figured it unlikely that MBAM was contributing to the problem, but what the hey it seemed no headache to uninstall it if I was only going to re-install it again later, "just in case".
So uninstalled MBAM. It didn't solve my problem. Never seriously expected that it would, but no harm trying.
Then I re-installed MBAM, and here is where it got interesting: I was not prompted to enter any licence key. Somehow it "remembered" that I was a paid-up user. Now, while that marginally reduced my admin in re-installing it, this does pose the question of whether my earlier uninstall was successful. Any ideas?
