Zonealarm
Nod32
Kaspersky
Which has the best detection/memory usage?
erm not dependent on costs, its still the best?
ZoneAlarm will work best a firewall for newbies.
NOD32 is for advanced users if you know Windows in and out very well, otherwise, you will be scared to hell by it.
Kaspersky relies more on signatures, so it's best for newbies.
Cost wise, ZoneAlarm is a bit stiff in my opinion. NOD32 and Kaspersky prices are competitive though.
With no restrictions to cost, I will choose NOD32.
so i duno about windows much.. dun choose nod32?
