I know this is a silly topic to post on this forum... ... but i've been a mac person since 1984 for my past seven computers and i really don't want to venture into any pc forums yet... sceptical of their usefullness... I have finallysuccumbed to the designers plight and bought a pc! it is an xi computer, dual amd 64 opteron... very nice all around... but i'm afraid to hook it up to the internet. i don't really have to, i think... i have a klm switcher to switch between the mac and the pc... the mac will be online through ethernet... and i hope i can network wirelessly to share files between the mac and pc using 801.11g. what do you guys think? is this overboard? if i were to connect to pc to the internet, which i don't really want to do because it is just for design and i don't want it to be encumbered with strange spamware etc, but if i have to for whatever reason... what is the best way for me to do so? firewall up... download firefox... what else? i don't know anything about pc protection. thanks, r.
