Hello. I am by no means an expert on A/Vs. I am using NAV and my renewal date is coming up soon. I have been trialing some A/Vs just to see what's out there. I just got through trialing NOD32 version 2. It ran fine on my computer, 3.5 year old Gateway, AMD Athlon 700, 448 RAM, XP Home, and it was pretty easy to use. Like I said, I'm no A/V expert. It's come down to either NOD32 or renewing NAV. I know it will probably be a little bias here , but can you tell me, if at all possible, which would be better protection for my computer and why? I could use some expert help.
