I'm about to install XP on my machine using VMware Fusion but am concerned about viruses and all the other crap Windows attracts. I'll be using XP for browser testing only so it won't be open all the time but I will use it quite a bit. I also plan to use the same install for Bootcamp to play games. I'm mainly worried about security. Will any viruses or malicious programs that may get on the XP install affect OSX, or are they well separated? What are some measures I can take to help keep OSX clean and safe? Thanks.
