Is MacKeeper a legitimate program?

I am concerned about this app named "MacKeeper". It's very weird, and I'm not 100% sure it's legitimate. Is it real or a scam? Here's a screenshot:

Is this app real or a scam? People here on Apple Support Communities think MacKeeper is a scam and they tell you that you must uninstall it now. MacKeeper displays a lot of distracting popups and notifications, and for doing almost anything requires you pay for the registered version.

It is malware

No, it's not. It's a legitimate app that has numerous major strikes going against it. Here's at least a few.


1) It's poorly written garbage that is well known to, and proven to hose many systems that were fine before running this app.


2) It doesn't do anything you can't do with other apps that are free, or can be done with functions already available in the OS.


3) The company's marketing tactics aren't just aggressive, they're heavily misleading, and outright fraudulent. The last being proven by the app's insistence of finding many "major" problems that needs to be fixed on a new Mac fresh out of the box.


4) The company selling this garbage has had two class action lawsuits brought against it. They lost both. Here's a note on one of them. In their favorite excuse, it's always the affiliates fault for all of the adware and other heavily pushed methods of getting users to buy it. Well, they pay the affiliates for the advertising. So who's fault is it?

Legitimate apps do not scam you into accessing your files so they can hard sell you into more costly services. I "upgraded" my MacKeeper but had to call an 800-number with an access number. That should have been a warning. Credit Card companies used to do the same thing, and then tried and sell you on lots of other services ... they stopped the practice because of public sentiment.


MacKeeper requires you to call an 800# before you can use their software. They told me they want to get it installed and show me how it works. But then all of a sudden they have a file-log they say if full of viruses that only an Apple technician can fix - an Apple technician they have on staff ... for an additional fee.


That's wrong. That's invasion of privacy. They scanned my computer and used that data as a sales tool against me. They said they were trying to help me learn how to run my software myself and wasted 10 minutes ... I was late for class - I skipped it altogether - who wants to walk in late? A real company sells the app, and lets the app offer an upgrade. They don't act like stormtroopers barging in and stealing data. I cancelled my MacKeeper account. It was easy - I just called the 800#. When they asked why, I told the operator that they had invaded my privacy ... and I was extremely calm. She kept fake happiness in her voice as she forced out, " have a nice day." I was impressed with her.

Nude pics of me from Kromtech. Am I supposed to thank them? Or sue them for the invasion of privacy?


Got a note a few days ago saying someone had unauthorized access to my Mac. They showed locations of that access with pics of the perp. Actually, 6 separate incidents. They finally noticed me on all of those in one day. They sent 2 more to me just now.


The perp was in 8 different locations within a 5-mile radius of my home. Some were close enough to be my house, others further away.


The perp was ME and, in 2 pics, I was nude.


They have gotten rid of lots of garbage, and found 3 questionable items, but

I am getting rid of MacKeeper.

That sounds like something you should take to the police.

That download had nothing to do with Flash. You installed adware. Hopefully, nothing more severe than that. MacKeeper is not on your Mac, but they are heavy users of such advertising.


Download and run MalwareBytes for Mac. It will look for and offer to remove any such junk it finds.


In the future, never, ever believe any site that claims you need to download anything from them to use their site. Any such message is a lie, almost, but not quite 100% of the time. Legitimate messages will tell you to visit Adobe to get Flash. There are no legitimate messages of any kind that insist you download and install software from them.


The one and only place to acquire the Flash Player, or to update it if you already have it installed is directly from Adobe.
