"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.

"ZipCloud," sometimes named "JustCloud," is a cloud-storage service with a doubtful reputation. The OS X client is sometimes distributed along with malware. Although ZipCloud may not be malicious itself, it should be suspected by virtue of the company it keeps.
To remove ZipCloud, start by backing up all data (not with ZipCloud itself, of course.)
Quit the "ZipCloud" or "JustCloud" application, if it's running, and drag it from the Applications folder to the Trash. Don't try to empty yet.
Triple-click anywhere in the line below on this page to select it:
~/Library/LaunchAgents
Right-click or control-click the highlighted line and select
Services ▹ Open
from the contextual menu.* A folder named "LaunchAgents" should open.
In the folder, there may be one or more files with a name beginning as follows:
com.jdibackup.
Move all such files to the Trash.
Log out or restart the computer and empty the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
