Over all the program is a very good one. You can optimize your computer and speed it up. However, for the cleaning and optimizing scan, I would uncheck the boxes labelled “registry clean” and “registry defrag.” I have heard too many horror stories of people trashing their systems because of messing around with the registry. You aren’t going to get any significant improvement in your computer’s performance so why run the risk? The best registry cleaner is no registry cleaner. Malwarebytes flags most registry cleaning programs including this one as potentially unwanted programs. There is probably a good reason for this. However, I have never had a problem with this program and don’t anticipate having any because I will not be using the registry cleaning or registry defragging components of this program. Good program. A little common sense needed.
