Norton AntiVirus AutoProtect: Potential interference with iPod operation
Some readers are reporting an issue where various iPod models are adversely affected by the AutoProtect function offered by Norton AntiVirus.
MacFixIt reader P.J. writes:
"Basically, if Norton Antivirus 10 (latest version) is installed, and if you have a 30GB slim latest model iPod, or a 8GB new iPod Nano, then when you attach the ipods to your Mac and iTunes starts, your iPods cannot sync nor update themselves. An error message comes up saying that the device is in use by another application. Also, you cannot eject the iPods from your system. Even quitting iTunes does not help."
"Of interest is the fact that older iPods (before this latest revision set) seem to work fine with no problems. This included a 20B iPod, and a 4GB Black iPod Nano. Thus, this would indicate an issue between the latest iPod firmware and Norton Antivirus Version 10.
In most cases this issue can be resolved by simply disabling AutoProtect from within Norton AntiVirus. Failing that, however, you may want to try removing the following files from /Library/StartupItems then restarting:
- NortonAutoProtect folder
- NortonAutoProtect.kextcache file
- NortonMissedTasks folder

Auto-Protect Mount Scan Preferences do not work as expected when mounting an iPodŽ using a USB port
Solution, uninstall that garbage.
Norton AutoProtect is also interfering with Backup. The Apple support board is reporting many, many "Archive is in use" error messages during scheduled backups. A check with Activity Monitor shows AutoProtect interfering with Backup as the application tries to write files to a designated external or secondary internal location.
LOL, another to add to the list. Thanks for the info, might come in handy in my travels.

I am getting "Cannot connect to DB server" message, resulting in double posts.
Does Macfixit have NAV installed? :D
The iPod was periodically freezing after disconnection. I returned it to Apple, who said it did not have any problems.
After I got it back, I have discovered that as long as I ensure that the iPod is unconnected (the menu has reappeared on the screen) before I disconnect the cable, I do not get the freezes. I have found that if the iPod has a problem syncing, if I cancel the AV scan it will usually sync on the next try. If ejecting the iPod fails, I find that ensuring that the AV is cancelled and checking my e-mail or something will generally let it disconnect on the next try.
I have a 4GB nano that never froze and was much more forgiving of how it was disconnected. However, the AV scan always runs when it is connected too.

Update to my previous post. The careful disconnections ultimately did not cure the problem, nor has the firmware update 1.1.2, which I installed recently. The issues continue.
:)
Clearly no one is surprised here.

I have had no problems with NAV10, although my iPod is the older iPod Mini.
Conflicts in OS X between various software and hardware is less than in OS9, but they do exist. They certainly are not limited to Symantec products like NAV 10.

- We wanted to let you know that Symantec has made the iPod fix and it will be released in the definitions update on Thursday. Thanks.
