Hello fellow Mac Users. I want to gauge everyone's thoughts on NAV for Mac. My Live Update subscription is about to end and I haven't decided if I want to renew it or if it's really necessary at all. What do you all think? I'm aware that most viruses are written for the PC, but are they any concerns out there that we should keep in mind? Are Mac virus definitions a necessity for safe computing? Or is it just a waste of money to renew?
