My wife uses her PC for surfing the net and email only. She has an older PC (P3 with 256MB RAM). and it has McAfee Security Suite on it, which really drains her limited resources! Since McAfee expires end of this month, I'm considering getting her NOD32 (along with a lightweight FW). As she is on her own all day long, I'm wondering if NOD's gui, alerts, and updating process are simple enough for a completely non-technical person?
