Bit Defender and Nod 32 too much resources

I'm running NOD32 as my on access AV and so far, I've been pretty
happy with it. I particularly appreciate its low resource usage.

I then decided to download BitDefender 8 Free as a second AV to use
for on-demand scanning. I thought this would be more thorough than
running it online using IE.

I discovered that even though BitDefender is not providing on-
access scanning (ie, virus shield), it still loads and takes as
much resources as Nod32.

So, if I keep BitDefender 8 Free for on demand scanning, I'm
consistenly running both AVs and using an extra 16,000+ kb of
resources even though it's not doing anything when it isn't
actively being used to scan my system.

Might I be better off just keeping NOD32 and using BitDefender
and/or TrendMicro for on demand scanning via the web?

And...why would BitDefender load files that take 16,000+ kb when it
is not being a virus shield and not being used on-demand?

TIA

Correction - in the last sentence I meant Bitdefender is not being
used "on access".
