Disk fragmentation is generally main cause of slow and unstable computer performance. Smart Defrag helps defragment your hard drive most efficiently. Smart Defrag not only defragments computer deeply but optimizes disk performance. With "Install it and forget it" feature, Smart Defrag works automatically and quietly in the background on your PC, keeping your hard disk running at its speediest.

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!

Again this is the incorrect download.

The link for this newest version game me the 3.0 build, not the 3.1.
Iobit site doesn't even have this build up.
This good tool runs only at WinNT or hiher, not on 9.x!
