I rather doubt that the avastclear.exe, as far as I’m aware is backwards compatible.
I don’t know if even a clean install of the latest version probably won’t remove it either. I referred to the avastss.scr on this XP system has a creation date of 19 August 2016, 15:01:50, that is relatively recent possibly the later end of avast 2016.
So avastclear.exe should be able to handle avast 2016, but will it remove that file, I don’t know only a practical test would prove or disprove this.
