Does anyone know about the Mackeeper? Is it needed to protect my mac?

Does anyone know about mackeeper?

it's crap and potentially dangerous. have a look @ this discussion.

And is it needed to protect my macbook?

against what ?

Don't download mackeeper!

1st: when you get the pop-ups, they will get worse over time. I heard from other people they even could'nt open their Safari anymore. The problem with mackeeper pop-ups is that they you can't view a website before you press some buttons of them (wich leeds to problems) and that they aren't pop-ups from the site you're viewing (so the site you're viewing don't get paid for it).

To avoid this pop-ups: download glimmerblocker!

Really search on internet if you can trust it (I also did), but you'll see it's safe. Really great software. Since I downloaded it, and put it on, I never got these problems anymore!

I never downoaded mackeeper but still the pop-up would show up more frequntly over time, really frustrating.

2nd: When you download it, you got some serious problems. It isn't good software at all. It slows your mac to a new level. I don't know what to do in this case.

STAY AWAY FROM IT, MACKEEPER AKA 911 BUNDLE ON APP STORE, WHY APPLE PERMIT THIS

EPIDEMIC CRAP OF INFECTIOUS SOFTWARE IT'S BEYOND ME.

MacKeeper is highly invasive malware that can de-stablize your operating system. It is also a rip-off.
