Hello, I've been using ESS v3 for the past year and I thought I'd try AntiVirus v4 beta. As soon as I installed it, I got a virus warning: "Startup scanner boot sector MBR sector of the 0. physical disk probably unknown TSR.BOOT virus unable to clean" This is probably due to the fact that when whole disk encryption is set up using TrueCrypt, it places the TrueCrypt bootloader in the MBR. Good thing that no automatic action was taken by the ESET AntiVirus! I think that this is something that ESET should deal with, perhaps with a whitelist of trusted/known boot loaders? Maybe it's also an issue for PGP whole disk encryption - can someone else confirm?
