Problem with avast installation and the keyboard (windows 10)

Some keys on my keyboard have stopped working properly. When starting the PC they do not work and after a while they work after pressing them many times.
At first, I solved it by uninstalling the keyboard controller and reinstalling it, but when I restarted the computer, it happens again.
Then I noticed that one of the controllers appears with an Avast signature (I imagine that to avoid keylogger).
[b]If I uninstall avast, the keyboard works correctly, but when we reinstall it and restart the pc The problem with the key returns

Could you help me on how I can fix it or I must to install another antivirus ???

Thank you.
