Sometimes whenever I do quick or full scan and then click my Firefox over Avast window to continue using it and let Avast scan run in the backrounf, Avast program window suddenly puts intself over my browser window at some point of the scan. This has been a thing for long time for me and hasn't gone away after Avast repairs trough control panel for other hiccups with the program. It doesn't feel like a big issue however, outside sometimes when Avast window pops up right when I'm about to click something in my browser and accidentally end up clicking "Stop scan" button on Avast instead.
