Ads to eliminate

it’s a big problem to see many ads on my screen… (left right!) is it a problem with one of my Avast softwares?? can you resolve this big problem?

First, I’m an Avast user and not an Avast Team member.
To try and help you will need to be a little more detailed.

Can you be a little more specific in what these ads are ?
What Avast Product/s are you using ?
