it's a Microsoft XP computer to the latest update (not my mac this time soz) i don't have any antivirus on it but its not connected to the internet so it shouldn't matter. its got a 2.66ghz processor and a nvidia geforce 5600(or something in the 5000's). my XP edition is the home one. soz that's all i know and sorry for not listening to your instructions. PS i tried switching keyboards and that didn't work
