I gone through your post it seems to be its a none McAfee issue because scan will not affect legitimate software . When you run scan it will scan for virus infection if its found one it will be removed or Quarantined.As per your request you would like to avoid scanning ipod it can be done in two ways they are.
1.While scaning your computer with McAfee when it reach the Ipod you can use skip button to avoid scanning .
2.You can also turnoff the schedule scan to avoid automatic scan but make sure you have to scan manually at least once in a week which is recommended.
Thank you very much for the reply. I appreciate it. Hmm, I wonder what the problem could be? Normally I'd just ignore it and figure it wasn't too big of a deal. But you know how those 'not too big of a deal' things usually turn into bigger problems in the long run. I'll head on over to the itunes forum and talk about what you've told me and see what they come up with.
Thank you again!
Ah, thank goodness this thread hasn't been closed yet. I've been talking with somebody on the itunes forum and the person helping me gave me a few things to try out. I was asked what other items are connected to a USB port and I answered my ipod, my mouse (has to be in a USB port instead of the mouse port because it won't fit in the mouse port), and a wire connected to my modem. The person came back and suggested I disconnect the wire from the modem, restart the computer and plug the ipod in and see if the error pops up. I did that and it still popped up. And the person said if the error still popped up it had to be an issue with an anti-virus program. Try temporarily disabling them and see if the errors pop up. I disabled McAfee temporarily and I tested my iPod out three different times. The errors didn't come up. It is some sort of problem with McAfee.
