How to uninstall MacKeeper from your Mac | Macworld

You do not need such software. It is not malware, but it isn't good for the computer.

1. It is a scam and very bad.

Uninstall it. Then restart.

"MacKeeper" is a scam with only one useful feature: it deletes itself.

First, back up all data.

Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.

If you have incompletely removed MacKeeper—for example, by dragging the application to the Trash and immediately emptying—then you'll have to reinstall it and start over.

IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.

In the Finder, select

Go ▹ Applications

from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the other functional components of the software will be deleted. Restart the computer and empty the Trash.

☞ Quit MacKeeper before dragging it to the Trash.

☞ Let MacKeeper delete its other components before you empty the Trash.

☞ Don't try to drag MacKeeper from the Dock or the Launchpad to the Trash.

☞ Don't try to remove MacKeeper while running in safe mode.

You may have installed ad-injection malware ("adware").

Don't use any kind of "anti-virus" or "anti-malware" product on a Mac. There is never a need for it, and relying on it for protection makes you more vulnerable to attack, not less.

This easy procedure will detect any kind of adware that I know of. Deactivating it is a separate, and even easier, procedure that doesn't involve downloading anything.

Some legitimate software is ad-supported and may display ads in its own windows or in a web browser while it's running. That's not malware and it may not show up.

Step 1

Please triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:

~/Library/LaunchAgents

In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. Press return. Either a folder named "LaunchAgents" will open, or you'll get a notice that the folder can't be found. If the folder isn't found, go to the next step.

If the folder does open, press the key combination command-2 to select list view, if it's not already selected. There should be a column in the Finder window headed Date Modified. Click that heading twice to sort the contents by date with the newest at the top. If necessary, enlarge the window so that all of the contents are showing.

Follow the instructions in this support article under the heading "Take a screenshot of a window." An image file with a name beginning in "Screen Shot" should be saved to the Desktop. Open the screenshot and make sure it's readable. If not, capture a smaller part of the screen showing only what needs to be shown.

Start a reply to this message. Drag the image file into the editing window to upload it. You can also include text in the reply.

Leave the folder open for now.

Step 2

Do as in Step 1 with this line:

/Library/LaunchAgents

The folder that may open will have the same name, but is not the same, as the one in Step 1. As in that step, the folder may not exist.

Step 3

Repeat with this line:

/Library/LaunchDaemons

This time the folder will be named "LaunchDaemons."

Step 4

Open the Safari preferences window and select the Extensions tab. If any extensions are listed, post a screenshot. If there are no extensions, or if you can't launch Safari, skip this step.

Step 5

If you use the Firefox or Chrome browser, open its extension list and do as in Step 4.

Everywhere in this forum everybody supports the use of the AdwareMedic tool to remove adware infections. The originator Thomas Reed is considered a very trustworthy security specialist. Since he converged with Malwarebytes company this software is called Malwyrebytes Anti-Malware. Use it. everybody here can support that.

Your question brings up the subject of removing adware. This is a general comment on that subject.

I am a member of this forum, and I do not support the use of any kind "anti-malware" product. I do not regard anyone on this forum as a "trustworthy security specialist," whatever that is.

The only tools that anyone needs to detect and remove adware are the Finder and a web browser, both of which you already have. Anyone who has enough computer skill to install adware can just as well remove it without using anything else.

Under no circumstances should you ever allow anti-virus software to delete something for you.

Apple doesn't endorse any third-party "anti-virus" or "anti-malware" product. Here and here are its general statements about malware protection, and here are its instructions for removing the most common types of ad-injection malware. None of those support pages mentions anti-malware products. An Apple employee who recommends such a product is speaking only for himself or herself, not for the company. See this thread for an example of what the results can be.

You become infected with malware by downloading unknown software without doing research to determine whether it's safe. If you keep making that mistake, the same, and worse, will keep happening, and no anti-malware will rescue you. Your own intelligence and caution are the only reliable defense.

The Windows/Android anti-malware industry had more than $75 billion in sales in 2014 [source: Gartner, Inc.] Its marketing strategy is to convince people that they're helpless against malware attack unless they use its products. But with all that anti-malware, the Windows and Android platforms are still infested with malware—most of it far more harmful than mere adware. The same can be expected to happen to the Mac platform if its users trust the same industry to protect them, instead of protecting themselves.

You are not helpless, and you don't have to give full control of your computer—and your data—to strangers in order to be rid of adware.

These are generalities.

If you purchased a copy of MacKeeper and you are "disappointed" in the product, you are entitled to a refund based on a recent class-action settlement.

You certainly are entitled to your opinion but credibility would be established with supporting facts.

I do not regard anyone on this forum as a "trustworthy security specialist," whatever that is.

Then is there any reason why any one should pay any more attention what you say as opposed to any one else?

Apple doesn't endorse any third-party "anti-virus" or "anti-malware" product.

But why don't you also include the fact that Apple has never stated, before or now, that third party applications cannot be used in problem solving. In that regard your statement is very deceptive and can easily lead to an erroneous conclusion.

An Apple employee who recommends such a product is speaking only for himself or herself, not for the company.

How untrue this statement is. Any employee whose job is to communicate with a company's customers is speaking for the corporation because that is their job. These include the persons who staff the telephone support service or the genius' at an Apple genius bar. When they recommend Malwarebytes Anti-Malware for Mac, they are speaking for Apple and many of them have made that recommendation. Why? Because they have found it faster, simpler and more efficient than the Apple support article that you seem wedded to. They work with such problems daily and I submit that they will use what their expertise and experience has shown to be the best approach in solving a given problem.

Ciao.

Well said.
