I have installed Malwarebytes Anti-Ransomware beta, and regretted it immediately. I have an Administrator account (Windows 7 x64 Ultimate), which I only use when I fiddle with something. I also have a user account, which does not have administrator rights, and which I always use when I want to do some work. Both are password protected (both different passwords). After installing MBAR my user account got screwed up, and I was left with only the Administrator account. Fortunately I had a backup image of the system partition, which got me out of trouble again. It seems this program is far from ready for prime time. I have seen Betas and their problems before, but this is by far the worst I have ever seen. What puzzles me, with all the problems reported here, I see no reaction from Malwarebytes!
