I have tried [removed competing product] in the past, but the latest version has too many paid for options that were free in the original version, which is no longer available.
It also causes malwarebytes anti-virus to identify it as a possibly unwanted program (PUP) and wanting isolate it.
It runs really quickly and the figures for hours taken by me on these programs are actual values, not predicated results.
The latest one that I do like because it enables me to do what I want to do which is defrag and optimise my drive to elimminate the hold up it causes programs in working.
It is [removed competing product], which does optimise as well for free, although its estimates of finish time can be widely out.
I can set up various options, including stopping it running on start-up.
I can also stop more programs being automatically downloaded.
It works a lot faster than CCLeaners, it has a better display of what is going on and can have a limit on the size of file being dealt with.
It works on regular basis, and I can manually do a check to see if it needs to be done.
They offer a computer registry and other clean-up utilities, but I can choose to turn these off if I want to use other programs.
The thing is to try various versions and not believe the online reviews (top ten etc), as these have a advert bias.
