Avast uninstall

Hello,
I used the Avast antivirus clear uninstall, restarted the laptop but it keeps showing with every restart or trning on a menu where can I choose to use operation system WIndows 10 or this uninstallation program. Any suggestions what’s wrong and what can I do to fix it?

Use the Run command use msconfig select Boot and delete the one that refers to Avast.
