I know that some people have a pc that they don't use for anything except their photography and related stuff, and they keep that machine offline so it can't be compromised by a virus or whatever internet nasties.
My question really is, "If you're one of those people, do you have anti-virus on that machine? Do you keep the OS updated?" It seems to me that, if you have a machine that's never exposed to the internet then you don't need anti-virus, and if the machine works fine then you don't need updates.
I'm about to become one of those people who have a pc that never goes online, and I'm interested in others' experiences and opinions.
