I've found out that if I install Windows 7 and use the Snow Leopard Boot Camp drivers (Which I need for the graphics chipset drivers.), the Mac partition appears and is read-only. I'm quite concerned about this, because if my Windows partition is infected with malware, it could be a possibility that the hackers could take data from my Mac partition, even if it was read-only. In XP, the drivers used to not be able to view/read-only the Mac partition.
Is there any way to turn off Mac partition support while booted in Windows?
