I don't *think* this is a virus, I think this is a computer thing, but thought I'd double check. I had just restarted after using adwcleaner to delete some stuff off the computer to make sure a toolbar was cleared out, and I clicked on 'settings' on my open firefox browser and got a 'dispatcher processing has been suspended' error box. My screen sort of locked for a few seconds before returning to normal, nothing seems wrong, but not sure what it means. Tried googling it, but everything was in such tech speak referring to it I had no idea what it even was, let alone if I need to worry about it or not! I've attached a screencap of the box. Thanks!
