I need to use internet explorer on either Windows 2000, XP, or Vista in order to access a web site to do my math homework for school. I only need to use windows for this one purpose other than that I will be using my mac as usuall so speed and performance is not a huge issue to me. The only thing I am worried about is any viruses that may infect my mac through windows. So my question is... -What program do I use to run Windows? Boot Camp, Parallels, other? -Should I run it natively or through virtualization? -Which version of windows should I use? Whichever one of these options is less prone to windows viruses is the one I want. Also I'm not sure if these questions have been answered in other posts but I couldn't find them so please bear with me. Any help would be greatly appreciated.
