In light of the jpeg virus prep, ive been updating everything. the uhm.. slightly illegal version of zone alarm pro 5 i got fucked some stuff up. really pissed me off, but i finally got it taken care of. i managed to get a legit copy, but firefox and my av didnt want to update. so i uninstalled it again. i searched the forum and found 'black ice,' and lots of posts about za blowing. ive had za for years, the free and the pro version. it takes a long time to start up, and doesnt play nice with games. ive got a wireless router w/ switch and my dsl modem. do i need a software firewall? which one should i get? do i need a hardware firewall? ive got 2 xp pro, 1 xp home laptop, and an imac on my network. thanks!
