It doesn't have the bloat Nortan and the others do. NOD32 is lightweight, but powerful. Most proper tests I've seen also rate NOD32 towards the top. Nortan isn't THAT far behind, but the larger footprint, along with that suite of junk leaves me picking NOD32 every time. If you already have Nortan, you could stay with it. But if you are looking to buy a new one, NOD32 all the way!
