Mouse Freeze

Some weeks ago my Licensed Avast Premium was updated to newest version of Avast, and I suddenly the mouse and keyboard frozee.

I uninstalled Avast and installed another virus program, but I have been using Avast for many years, so this morning I unistalled the other virus program and installed the free version of Avast.
Everything works fine, but after a boot scan, the mouse freeze’s again.

Dear Avast what to do?

try a clean install … remove with this https://www.avast.com/en-eu/uninstall-utility then reinstall
