Hi, the thread title says it all. I know the Mac OS is pretty solid, but I'm still nervous about spyware, hacking, etc. The PC I'm sharing with has been sick several times (a big reason I've switched the Mac BTW). I'm running 10.4.10 and have set up the firewall. Anything else I should do? I guess I'm worried that since the PC has been targeted the Mac will be too as they're on the same network. Keep in mind I don't know much about how networks work and how this stuff works in general. Any help or reassurance is appreciated!
