I think AVAST should include a close button on the notification pop-up boxes that appear on the lower right corner of the screen. It’s kinda annoying that to make them go away, you either have click on them to open, then close or you have to wait until they dissapear.
I agree…
Anyway, there are ways to configure the panel or even removing it: http://forum.avast.com/index.php?topic=1647.msg10268#msg10268
