It's time to renew my annual subscription for Norton Anti-Virus. I'm running the 2003 version. I'm very, very, very, computer "challenged". Thinking about upgrading to the 2005 Internet Security package that has a firewall. Currently I'm using the MS firewall that came with the XP software & I have a dial-up connection to the internet. Would I be wasting my money on the upgrade or is it worth the extra bucks? Any advice and help will be appreciated.
