If anyone knows about these snake oil programs Mr. TwinHeadedEagle does. I agree with him 100%.I would council you to stay away from such programs like ASC or TuneUp. What they are doing isn't needed at all, and there is a chance to break something. I have never used them and I do not see need to do it.
Just keep using them and sooner or later you will have to restore your OS.
FYI TwinHeadedEagle is MT's malware fighter and he's the best I have ever seen. IObit doesn't have a very high rating here on MT.
