I use WiseCare 365 Free, it is more polished. I checked Toolwiz Care and it did not find much to clean after WiseCare, though I liked the realtime monitoring, but that is that.
CCleaner Defraggler WiseCare 365 - I like everything except it's drive defrag, which is why you see Defraggler on the list. PrivaZer All free and they actually work without any problems
