Newbie question: Any need to boot from CD for a "clean" scan?

peterpqa
I'm a brand new user of Sophos AV Mac Home. I searched the forums on "boot" and "startup" but found no info on this issue... I've always been a Mac user at home, but I used Windows machines at work 'til 2002. To properly scan a Windows machine, we had to boot it from a CD or a locked floppy so we could scan for boot sector viruses. If we booted up the Windows machine from its hard drive and ran a virus scanner, it couldn't see that malware. Is there a need to do this on a Mac? That is, if I boot my Mac normally from my hard drive and run a Sophos scan, are there certain files and/or firmware that Sophos can't scan because they are "in use" or otherwise inaccessible, and would they be scannable with a boot from CD? Thanks, Peter

    You can think of EFI as being "Enhanced Open Firmware" -- OF doesn't have as strict a security model, but it is also unlikely that someone's going to write Forth malware for it at this point, so the issue is moot.  If you want to improve security for it, you can password protect your Open Firmware; that will protect you from any theoretical malware.
