What cleaner works with SAFEZONE besides the monthly pay AVAST one?

Ever since I have had computers, I have used CCLeaner but using AVASTs odd hybrid SAFEZONE broswer, I do not see it acknowledged by CCleaner. Does anyone know what is effective on keeping it and the system clean as well as CCleaner…preferably free??

The idea of the SafeZone Browser is that it is isolated from the system, which is why you can’t install extra add-ons that aren’t already installed by avast.

I would presume this isolation from the system would apply to CCleaner that would be trying to access it installed location.

I would hazard a guess this would apply to other external cleaners. As I don’t use the SafeZone Browser, see what internal settings it has for clearing browser cache/history, etc.
