Is the MacKeeper safe?
The short answer is NO!
MacKeeper is malware. Although it advertises itself as a way to secure, clean, protect and optimize your Mac, it often does the opposite!
Apple designed macOS and OS X with security built-in. So if you keep your Mac up-to-date with all the latest security updates, your Mac should remain safe and secure–with no need for a third-party tool. If you decide you do want a third-party antivirus or malware tool, look for trusted sources like Norton.
When Did I Install MacKeeper?
You probably don’t remember installing it at all! Most people don’t.
Some of our readers believe that MacKeeper was installed on their Macs after downloading what appeared as an Adobe Flash, Reader, or other Adobe Software Update. 
We’ve seen many reports of fake warnings that your Mac’s Adobe Software requires an update–and in that update is packaged MacKeeper.
Of course, Adobe does NOT bundle MacKeeper with the Flash Player installer or any other Adobe product. So when you see a message saying an Adobe product needs to be updated, always go to Adobe’s website to confirm an update is needed.

Getting a message that MacKeeper can’t be removed because it’s open? 
If you see this message, that means you have not successfully closed out of MacKeeper. Follow the instructions above in the section The Never to be Seen Quit Command.
Still Seeing MacKeeper on your Mac? Can’t Uninstall?
Try Safe Mode
If you’re not able to follow the instructions above, reboot in Safe Mode. When you restart your Mac, immediately press and hold the Shift key until the Apple Logo appears on-screen.
Safe Mode temporarily disables any malware, prevents startup items and login items from opening automatically and deletes your Mac’s font caches, kernel cache, and other system cache files.
Then try running through the uninstall steps again, but this time in Safe Mode.
To exit Safe Mode, just restart your Mac normally.
Use Some Terminal Commands to Uninstall MacKeeper
- Open Terminal via Application > Utilities > Terminal
- Type in the command: ls
- This command lists all of the directories available
- Type in the command: cd Applications
- This command goes into the application folder
- Type the command: ls
- Look for MacKeeper.app
- Type in the command: rm -r MacKeeper.app
- This removes the MacKeeper app from your Applications Folder
- If a browser window opens with the MacKeeper uninstall survey, exit the survey without answering and close your browser session
- Quit Terminal
Try a Third-Party Tool 
If the steps above did not solve your problems with MacKeeper, our readers recommend using a third-party tool called Malwarebytes’ Anti-Malware for Mac. Unlike MacKeeper, Malwarebytes is legit–but don’t take our word, please check out reviews before you download!
Other third-party options our readers use include DetectX or DetectX Swift, which are both shareware.
Reinstall macOS or Mac OS X 
Some users tell us that reinstalling their macOS (or Mac OS X) solved their problems and cleared out MacKeeper.
First, back up your Mac using Time Machine or your backup method of choice.
Then to reinstall, start-up in macOS Recovery using Command+R keys and choose Reinstall macOS (or Reinstall OS X) from the utilities window.
