Last night I uninstalled my security software on my Win 7 computer except MBAM-2. I then tried to install the Beta Version over MBAM-2. It ran good until I did a reboot. Then I got warnings of real time being turned off, Couldn't open IE, F/F or Chrome. I couldn't shut down the computer, no reaction, everything froze. I had to Hard Shut Down. Started computer back up and the same problems. I tried to uninstall the Beta version, no reaction would not uninstall. Did another Hard Shut Down and went to Safe Mode to Uninstall. Started the computer, used Revo Pro on left overs of MBAM, reboot. Did a CLEAN INSTALL of MBAM Beta. No problems now, running good after many reboots.
