I’m mostly Mac at home but do have a Win XP laptop I have used with instruments and for programming. I’ve never networked it or used it online, and never put any antivirus software on it. It’s amazing how fast it boots, and getting things to work is often easier on it.
If I wanted to use it on my home network (with always-on broadband internet), how important would it be to install antivirus and other security software? Let’s say I might not even browse with it, but only use it for non-Web purposes. Or let’s say I might browse a little, like looking at major news sites and coming here.
I read recently that according to Symantec about 30% of small business computers run no antivirus software. This is amazing - I’d have guessed something like 1%. And I’ve heard elsewhere that antivirus isn’t necessary anymore, or only in some circumstances.
What say the Dopers?
