Hello My first post Antivirus software on macs, is it necessary??? I'm thinking of 'switching' and was just wandering how many of you hardcore mac users out there have some kind of Antivirus software running on your macs? I'm looking to buy a 12" iBook or Powerbook. I know macs are nowhere near as susceptible to viruses as Windows machines but I'd like to know If I should be concerned and run some kind of Antivirus when I do get my mac. I've read on some sites that macs are becoming targeted more. Cheers.
