We-e-e-lll, upgraded over-the-top to 11.2.2261 just now in Admin, seems to work okay in User. Like the GUI, it seems more intuitive than previous. I can't really make any complaints as I've kept the minimalist settings from the previous 2015 edition, just File Shield and Home Network Security.
@Vlk - Please, when scanning/"fixing" the hosts file, can Avast! only remove single entries? Deleting the entire file suddenly extinguishes my own security methods, exposing my browser to places it shouldn't redirect to... Problem is that some/many of the entries may well be entities that Avast! doesn't like, but because they're pointed to 127.0.0.1 they are by definition harmless. You should look for that before you do anything else.
System is in sig.
