Windows says the app isn't signed.

Where did you download CCleaner from? Just want to make sure that it's genuine before continuing.

SmartScreen will sometimes throw a block for a day or so after a new version of CCleaner is released until Windows Security Centre gets updated with the new signatures, etc.
But CCleaner v5.76 has been out for a week and no one else has reported this problem.
(Are you using a metered connection? If you have told Windows your connection is metered WSC definitions won't get updated).

Try downloading the 'Slim' installer (3rd down) from here and install using that:

If it's still being a problem try updating Windows.
Or if you are sure that your CCleaner is genuine, eg. you've downloaded the Slim installer from the builds page, then simply ignore Smart Screen, close that warning, and carry on installing. (I've had to do that once before without any problems).

Worried about 'Tracking Files'? Worried about why some files come back after cleaning? See this link:
