So lately I have been seeing more and more antivirus apps popping up in the app store. I know that apps have to go through apple and be approved before they are put into the app store but what about the internet? Let's say you go to any and every site you come across (I don't but theoretically speaking) do any of you think an antivirus app is necessary, or does the iPod serf the internet in such a different way than most devices/computers that it is of no use?
