ok i know that you know some ipod videos came with viruses as it says:

http://www.apple.com/support/windowsvirus/

now if a person already has avg antivirus installed,and a ipod with this virus is connected to the pc,what would happen? will the virus start to spread straight away or will the antivirus pick this virus up? and would it be able to remove it from the ipod or just the pc?
