Adds crap when installed & also adds 2 startup entries - You can do far better than this, mostly used by IOBIt to get you to try their other products.

Smart Defrag needs to stop including the PUP Open Candy.
This is like the 3rd time MalwareBytes has flagged this PUP during the Defrag download on BetaNews.

It's definitely faster by far than any other defragger I've used, and it's passed scrutiny at Gizmo's and Major Geeks. In spite of one past instance of malefaction, in which IOBit was caught stealing code from other security software companies, and although I have yet to install this very latest version of IOBit defrag, I am reasonably comfortable giving it a...wait for it.....5!
This good tool runs only at WinNT or hiher, not on 9.x!
