how to update out of date drivers automatically
First, I’m an Avast user and not an Avast Team member.
You don’t say if you have a driver Update
Avast does have a Driver Update program (and there is a sub-forum related to it), which isn’t a free program and even so there are some drivers it isn’t able to update.
However this is the General Sub-Forum and that doesn’t give any clue as to what Avast program/s you have ?
I actually did a Google Search for your Subject Title - might be worth a look.
