No email protection by choice

I was wondering. I'm about to load nis10(cd) over nis08(pre-installed) and figure if I  use only windows

live mail as my mail client I can probably disable the mail protection in nis10 and save a few cpu cycles

and some ram. Would that be a waste of time? It's my understanding that norton doesn't protect w.l.m. and

never has. If that's true will protection be available someday. Thanks.
