This is one of those bait-and-switch deals where they use the magic word 'free' to suck you in, then it turns out that means they give you a list of thousands of temporary files that you can delete manually, and in my case a list of only about 50 registry entries that I could delete if I wanted to. But the app itself displays a big green tantalizing 'fix all items' button that takes you to a purchase page instead of fixing anything! Yeah yeah it's legal enough but it's goddamn insulting to be treated like a mark to be conned. Especially considering tt there must be a thousand utilities out there that will do the same thing for free. My guess is that 95% or more of these reviews are fake, because nobody like these kinds of marketing come-ons that for all practical purposes constitute scams.
