Hi,
if it happens again I'll send you the capture.
However, I don't see the point of showing you this screenshot because it's the official avast UI that opens as it does when we accept offers in the privacy settings.
the 1st screen offers us 3 choices (3 rates): 1 year , 2 years (suggested) and 3 years.
If we close this screen, for insist there's a 2nd screen offering 60 days free with the "time" slider at the bottom.
If we close this screen, we return to the avast homescreen with "this computer is protected" and "launch smart scan".
