Hi, I want to install windows xp pro with sp2 using boot camp on my macbook. All I will really use it is to play one online game which is battlefield 2, other than that i plan to use Leopard OS. My question is, will i really need internet security for the windows partition? even though im just using it for one game and no browsing at all? If so, what are some good free programs so i wont need to buy one. Also, if windows for some reason does get a virus and is affected will the Mac partition also be affected? too many questions sorry, its my first macbook and dont know much about it.
