@NON
sorry, the annoyance I was talking about was not related to what you were saying about colorblind people (no doubt a confusion in what I wrote due to my bad english) but to the visual annoyance that the new interface can cause.
I repeat, personally I don't mind, especially since I don't use password.
@DavidR
I no longer have a screenshot of the old UI to give a comparison, but what is certain is that the home screen (with "this computer is protected" & smartscan) has become thicker and bigger (more flashy) as said by other users.
On the other hand the colors have not changed, if that's what you want to know, it's just a little brighter/contrast to my eyes.

You may need help directly from Avast.
As you said
here it's not always easy to contact avast to re-install password when you have a free version of avast , even more difficult when users are in foreign sections where no contact with avast staff on the forum is possible
