Some suggestions here, see link

"First off, open up MacKeeper, then quit it (activating an account is not necessary). This will ensure that the program is closed. After that, drag the program into the Trash. If you're not on an administrator account, you'll need to enter an administrator's password. This will cue the uninstall process, which is self-explanatory."

"Next, go into your username folder, then Library --> Application Support. You'll find a folder called MacKeeper Helper. Toss this folder into the Trash, and it'll also take care of a NoticeEngine.plugin file. Empty your Trash right away, then restart your computer. That should take care of MacKeeper, and you should strongly consider replacing it with Avira, or another legitimate antivirus product."

Thanks Zep516. I have quit it already and dragged into the trash. Nothing happened. It wasn't trashed. No password was requested and I don't believe I am on an administrator account as I am the only one who normally uses the computer. Where do find the username folder and library? I will admit to being clueless at times but I have never had trouble deleting stuff before.

Not a mac person so I'm Googling all this,

How to find the Library folder on Mac?Use “Go To Folder” and Open ~/Library/ Directly. All you need to do is hit Command+Shift+G from the Mac desktop (or Finder > Go > Go to Folder) and type in ~/Library to temporarily access the Library directory in the Finder. When you are done, close this window and it will no longer be visible.

And pasting the information in.

Sorry Zep I should have thought of that. As I said I am clueless. Thanks again!

If none of that is helpful, start at the beginning by Googling

"How to delete MacKeeper"

You may find a good set of instructions.
