Without Boot Camp this is all just speculation on my part, but I find it incomprehensible that fdisk could access and modify the Mac partitions, and I attribute that utility with more powers than any malware. The base emulation layer, where EFI emulates a bios, loads before fdisk, a dos era boot sector virus, or anything else.
