I am delighted with the new Avast design style. My version is 17.2.2288.
I use OE6 as my workhorse email program - I have others , but OE works well with no hiccups.
My OE failed suddenly saying the server could not be found. Never happened before.
I got a clue from the web for similar failures and it suggested my AV was affecting it. Well it was.
I cut out the Mail Shield for 10 minutes, tried my OE and it worked perfectly. When I set the Mail Shield for permanently ON again, OE worked OK and has been OK ever since.
So Avast stopped my OE - why ?
