I just got my MacBook a week ago and I am about ready to get cooking and making it feel like home. I know a lot that I read and heard about Macs is that it's virtually impossible to get viruses and adware and spyware. I'm still not really convinced, and I would like to run anti-virus software. I want to run a free application. Can anyone suggest one? Also, and I'm not sure if this is allowed, it probably isn't, but just delete this if it isn't, does anyone know of a good free p2p program? I'm talking no spyware, no adware. Thanks. And I apologize if that isn't allowed.
