Make a Boot Camp partition totally impenetrable? I'm thinking of setting up Boot Camp on my early 2011 MBP for gaming purposes because, obviously, VMs just don't cut it when they have to share their hardware with OS X. However, several forums I've read say that a Boot Camp partition could make the computer susceptible to malware that can somehow access the OS X partition. Short of using two separate drives, is there anything I can to totally isolate the partitions from each other, or otherwise keep the OS X partition totally safe?

Some links about it.
If your Mac OS partition is encrypted with FileVault 2, it will be unreadable when you are booted to Windows. At that point, the only thing malware could do to this partition would be to wipe or delete it.
