I'm sorry - but CCleaner has become very annoying on Android with the constant ads and bogus notifications of "needing to be run" again and again and again.
After the new update the cleaner just sits and hangs for a while on Internet Explorer Cookies - and comes up with nothing because I do not use IE. This was an annoyance with versions in the past. I will be reverting back until a new version fixes it again. Grrrrr
