It sound like you are using CleanMyMac. If I am wrong please disregard my post.

Delete CleanMyMac immediately using their uninstaller. It won't delete all files and will require more work on your part to fully delete it. CleanMyMac is malware and causes numerous problems with your computer. Just a simple search on these forums will confirm this and offer solutions to fully delete.

If you need help installing or are still experiencing issues after uninstalling, we are here for you.
