From over here in Mac land, I run the Norton Anti-virus thing once a week (auto-scheduled). I have it limited to checking my mail folders and “Dloads”, where anything I download automatically gets dumped. Is there a reason to scan anywhere else? The few times it’s found anything, it’s been a Windows attachment virus, which Norton detects (and “quarantines”) even on the Mac, even though it’s entirely harmless here.

Activating a firewall is as easy as checking a check-box.

Keyboard shortcuts are supposed to be a whiz using Quicksilver, which many of my friends swear by. I had a bad experience with it when I first got my MacBook and haven’t tried it since. Maybe I should… :)
