Is Avast slowing anyone’s access to Amazon or Facebook?
First, I’m an Avast user and not an Avast Team member.
Not knowing anything about your system, it is hard to comment, however.
I use Amazon quite a lot and don’t see any real slowdown. I have Win 10 and a relatively old laptop with limited resources, description in my system details below my post.
I don’t use Facebook, I haven’t got an account, so I can’t comment on that.
