Can I be honest?
Norton and McAfee both suck when it comes to firewall protection, and virus scanning.
I prefer Nod32. It's relatively inexpensive, and it's insanely quick. Also it doesn't bloat up like the other security suites.
I'm sorry I didn't try to help earlier, been busy with other crap.
If you're a computer person, can you please contact me on AIM or something. I think a few of us need to get together and write a X5World FAQ on regular computer maintenence.
