Does Mac Keeper cause trouble.

It does indeed. If you have it installed, remove it immediately:

If you don't, never install it!

From the Safari menu bar, select

          Safari ▹ Preferences... ▹ Extensions

Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.
