I know what you all are thinking. And I know. My main concern is that I dont want to "Transport" windows viruses from my mac to my pcs / clients PCs. I know that OSX does not have a virus or whatever, I am not worrying about being infected myself. However 99.9 % of people I receive email from etc use windows, and since I take my iBook Everywhere and now going to be getting an IntelliMac, I dont want to receive these files, just to mail them off again and or store them on my machine. So what is a goood virus software? I guess for Intel Macs too?
