Avastclear didn’t remove Avast NG folder after uninstall of 2016 (tho it might, had I selected Avast program files folder [which doesn’t seem usually required]). Rejzor’s utility got rid of it. Manual delete would work, as well?
Avastclear does remove it after 2015 uninstall - or, maybe, uninstall did?
Still don’t know what it was there for, and guess I never will.
