khado made the point that he doesn't want the program to start on boot, therefore the heuristics detection won't be running. Kaspersky relies heavily on signatures, so may be more suited to on demand type scans.
Much of the choice comes down to personal preference. I tried 6 major AV's by imaging my system and then trying each in turn. You have to find one which does not slow your system and also suits your style. Kaspersky or Nod32 are both excellent.

It doesn't just rely on Heuristics, it uses signature based analyst techniques also. The program footprint (memory) is between 23kb and 50kb depending on what level of threat detection you want to run, and therefore has one of the smallest footprints out there. I have pretty much everything running at the moment, and NOD32 is only using just over 24Kb
From a security point of view an anti-virus program that is passive (on demand, and not loaded into memory) is simply not effective enough as it cannot prevent infection, it can only detect (and hopefully remove) after the fact.
NOD32 is not the only program out there that can do this with minimal use of resources, but from experience I would have to say its one of the best, and worth every penny I spent on it.
