I didn't have any problem regarding of putting my browser in the active mode check list. I know how important it is using "active" filtering mode. But I was wondering, what big differences does it have if browser was just left in its default setting of not putting browser in an active mode protection filter? Will NOD32 still scans the browser effectively even if it's just in the default "passive mode" filter? What it'll possibly miss if it's just left in the default passive browser protection mode? I am also a bit more interested with your personal experiences rather than just relying on the "technical" side of explanations.
