I plug in my iPad to my Windows 7 PC and iTunes starts a backup of the iPad. When backup is completed I receive a Norton Security alert that indicates a "Downloader.Upatre" infection and I need to reboot my computer to resolve the issue. This happens EVERY TIME I plug in my iPad. I never receive any other alerts similar to this one. Why is Norton Security seeing my iPad or iTunes software as a High Risk threat? Note if I start iTunes and don't plugin my iPad I have no alerts.
