i woudlnt get it for many reasons. 1 dont worry about viruses on macs. 2. the firewall is built into mac os x,and mac os x is hard to crack. so unless you have pentagon files and someone who is breaking in to your computer for a reasons then i woudlnt worry. 3. if you have to have viruses protection software, just buy .mac, much better service and virex is updated monthly.
