I have been using Malwarebytes Pro for a few years but it has recently started to make my system hang at the "Welcome" screen after logging in. I am running Windows 7 64-bit. I boot into safe mode fine, then uninstall it and it lets me log in just fine. I downloaded a fresh copy from the website and did definition updates and rebooted. Again, it makes my system hang at the "Welcome" screen.
Any idea on what could be causing this?
