Beware: MacKeeper is highly invasive. Simply put, you do not need it, and just go and read all the comments regarding problems people have had, including slowdowns.
But apart from that, is there anyone here who is not sick of MacKeeper's plethora of browser popups, redirects, spam pages and trick links? Even if this crapware sped up my system by an order of magntitude, I would not give these hucksters (Zeobit, now chaged to Krontech Alliance) one dollar for it. But no, it doesn't do that. What it can do is seriously damage your OS. Just google MacKeeper+damage and see how many people have suffered that consequence.
And then there are the fake reviewers that have saturated the internet with glowing testimonials. Just have a look at mikochiko (above) for an example, and in the 19 pages of this thread, there are many other shills. On their FaceBook page, they hide any remotely critcal comnents. Now ask yourself - would you install something that roots itself deep in your OS from a company that resorts to such unethical practices?
So to mimochiko and your merry band of shills and hucksters - please go away. We are onto you here.
