Question to clarify what's going on when I use a Win7 Bootcamp installation in Parallels 7. If I never boot into Bootcamp then presumably I am protected by the OSX Firewall when I am using Parallels. Yes ? As I am still using Win7, then I will still be vulnerable to Win7 related virus issues etc, so I will still need an anti-virus programme. Yes ? If I never use Email or any Browsers in Win7, then I'm unlikely to get a downloaded virus either. Yes ? So my Win7 "risks" are from Win programmes that "call home" to dubious sites. Yes ? Thanks.
