Re: Virus attacks on PGP

Certainly having PGP run from a CDROM or other read-only device would be a big help. Even better would be to have all the privileged code also run from a read-only device.

Seeing as PGP is quite small the simplest and cheapest read-only device would be a write-protected floppy disk. Could a virus write to a write-protected disk? I'm not sure if the protection is done in the BIOS or the drive hardware.
