Question

After loading Maverick iTunes will not launch.  I get an error code: -45054.  I am the administrator and have no groups or guests.  Sharing options don't fix this.  Also Fetch will not launch, I get error code: SSL error 9807.  These worked perfectly before installing Maverick.  Also everything that loads, all programs, take twice as long to load.  I have MacKeeper and have cleaned and discarded all the garbage. 

Answer 1

Remove "MacKeeper" as follows. First, back up all data.
"MacKeeper" is a scam with only one useful feature: it deletes itself.
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 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 functional components of the software will be deleted. Reboot.
☞ Quit MacKeeper before dragging it to the Trash.
☞ Don't empty the Trash. Let MacKeeper delete itself.
☞ Don't try to drag the MacKeeper Dock icon to the Trash.
