Borg11 speaks about build version by error like some others.
That said, avast should not indicate it so visibly, this is confusing
However in "about avast":
17.1.2286->built-17.1.3394
17.2.2288->built-17.2.3419
17.3.2290->built-17.3.3442
17.3.2291->built-17.3.3443
17.4.2294->built-17.4.3482
And , a lot of issues related to some devices (USB or LAN) blocked by web shield in latest avast version , maybe your case ?
