getting rid of Mackeeper

I have different symptoms that I think are related to MacKeeper, perhaps to other stuff my son has inadvertently let slip onto his hard drive. He turned on his MacBook yesterday only to find two thirds of his screen occupied by a crazy image (attached). If I try to install something from a thumb drive, its icon is behind this image. I can kinda see the cursor behind the image, but I can't find the installation dialog box to drag into plain sight.

Anybody else had something like this? Any ideas of remedies?

Thanks!

Thanks John, your tip did the uninstall MacKeeper plus the mega backup. I'm glad I never ran it or encrypted files. Just don't think any of that software is necessary since I always update current IOS and iTunes security updates from Apple.

Allan, I think I figured it out. Mackeeper andj Chum search or something had replaced the home pages on safari and chrome. I went in and deleted all the cookies then changed the home page URL. Think the ghost in the machine is gone now. Thanks!

Hi. Had the same problem and tried all the manual techniques. In the end the only thing that helped me was DetectX. I was skeptical about installing another piece of software to get rid of malware but it worked and have no problems yet :-).

Hay Guy, there are many ways to remove MacKeeper Adware.

(1) You should Safari update and Security update.

(2) Search MacKeeper website, and then cookies policies, if you see " I refuse " button. Click these button.

(3) Safari Preference, Privacy, Manage websites data, remove Ad pop up cookies.

(4) Clear Safari History.

I followed Allan's instructions below and yet, when I go to Safari, there is the Mackeeper prompt under the Search Box. It is still buried somewhere on the Mac. How do I get rid of it 100%?

You may have adware that is giving the MacKeeper prompts. Have you done anything to remove adware?

Deleting the downloaded installer file does not uninstall MacKeeper. Uninstall it by following its instructions, explained and illustrated below.

Follow these instructions to uninstall MacKeeper. They have been tested with the most recent version of MacKeeper. Earlier versions than the one released in 2012 required more extensive work to uninstall all its components.

If you actually used MacKeeper to alter your system, e.g. "remove excess binaries" or such, you will need to reinstall OS X as well as all your additional software. Uninstalling MacKeeper is insufficient to reverse the corruption it is capable of - once again, that is if you used it.

If you merely installed MacKeeper but did not use it to perform any particular action, the following instructions will suffice.

• If you used MacKeeper to encrypt any files or folders, use MacKeeper to un-encrypt them first.
• Quit the MacKeeper app if it is running.
• Open your Applications folder: Using the Finder's Go menu, select Applications.
• Drag the MacKeeper icon from your Applications folder (not the Dock) to the Trash.

You will be asked to authenticate (twice):

You do not need to provide a reason for uninstalling it:

Just click the Uninstall MacKeeper button. You will be asked to authenticate again.

After it uninstalls you may empty the Trash and restart your Mac. All that will remain is an inert log file that does nothing but occupy space on your hard disk.

This worked! Thanks!
