How to delete your peace of crap from mac os?

Hi, can somebody tell my how to delete ccleaner.app from the mac os? There is no exit button in the app, when I want to force stop it from activity monitor it runs up again. And therefore I can't delete it from Application folder. It writes The item “CCleaner.app” can’t be moved to the Bin because it’s open.

I don't needthis scam, bulshit and full of spam ads software on my mac anymore

I don't use a Mac so at the moment the only help I can offer is this.
