Noted, i will give the beta 19.6 a go hopefully that annoying pop-up goes away
To run the beta simply download the latest beta and install over the stable version, However, to return to a Stable version from the beta, you must uninstall the beta via Control Panel/Programs and reboot, then use the Avastclear.exe cleanup tool (choose 'Safe Mode' when asked) then reboot again, and then install the stable version again.
