My task manager shows two processes for NOD32: nod32kui: 1352 K nod32krn: 23164 K Several users report NOD32 to be light on resources, but I cannot understand why: ~23164 K is a lot!. Is this normal? Luckily for me, I have 1GB RAM and this barely (or never) impacts on my pc's performance. But I think it's a whole lot and is quite the opposite of "light on resources". What are your values?
