You don't really need one if you avoid risky sites, generally. I mean, in my experience, I've seen people overrun with mal-ware and/or viruses - to be people getting free music downloads etc.. Anyhow, it is true probably that music companies, textbook companies - put the viruses there on purpose - and maybe that's despicable - BUT, those not going there - simply have few/none virus problems.
Now, myself, as mentioned in another thread, use anti-malware, even though I don't surf P2P software (Napster etc.).
