I've been using a trial copy of Symantec Personal Firewall and Anti virus that came with my router, and my computer takes forever to load and shut down now. Plus I see all sorts of Symantec stuff running in the background. What are the recommended alternatives on both fronts? Of course Zone Alarm seems ubiquitous, but I've also heard good things about Tiny Firewall. And Zone Alarm now has Anti Virus as well, from what it looks like. It's for a 1Ghz laptop running XP pro.
