I apologize if this question has been asked numerous times in the past. I am thinking about downloading the new version of Nod32 with the new firewall etc. I am behind a router and I feel safe using the Windows XP built-in firewall. Will this new version of Nod32 be more lightweight using the new firewall? Do I need to do a custom install of Nod32 or is there a way to turn off the firewall when the program is installed? By the way, I am using an iMac running Windows XP Pro in Apple's Boot Camp. TIA.
