So I have a fresh new slate..I dont want junk on here like spyware, virus etc. I realize there is only so much you can do. But what do yoyu all recomend to best protect my system. I am using the Firefox as an internet browser (told it protects against spyware better...) I am running Zone alarm firewall. It's a trial for 15 days, is it worth buying? I have a trial version of Nortons... Is that worth buying too? Should I run an ad-aware type program every so often? What else should I do, or what should I do differently? Thanks!!!
