Well, just had my first popup after the 'repair/update' suggested above.
Nothing changed. Still can't get rid of the popup except by a screen refresh, ESC and X still don't do anything. Just have a useless lump in the bottom right of my screen, still telling me I have rogue programs that don't exist on my computer and the thing will only go away when I refresh my screen.
Haven't rebooted yet as I still have things running I don't want to interrupt.
