Hello avast team
in the French version, we have a bad translation in the setting.
here is a screenshot
best regard
Confirmed, same here (German).
Note, translation will be added next week.
the translation has just been done tonight for me 
On the other hand, the translation does not correspond to what is (was) indicated in English.
It is no longer a question of sending or requesting to send the files to threat labs but simply to block threats (without sending them to the threat labs)
