Can't restore iPod Classic 120GB

Update: My iPod has successfully been restored! Norton Security was in fact, the issue. When I tried to disable it earlier, I only turned off the Smart Firewall feature. Fully disabling Norton Security requires both the Smart Firewall and the Auto Protect features to be disabled. Once I disabled both features, the iPod began restoring.

Thanks again for your help!

I have a 120GB iPod Classic (not sure which generation) and Norton Security with Backup runs on my laptop. Norton seemed to have interfered with the restoration of the iPod but once it was temporarily disabled (via Auto Protect and Smart Firewall) the iPod was able to restore through iTunes. I enabled the Smart Firewall and Auto Protect and now everything is working normally again.

I have Norton Security as my anti-virus.

I disabled Norton and tried to restore but I still got the "iPod cannot be restored because it contains files that are in use by another application" error.

Also, I checked the HDD stats. They are as follows:

Retracts:2900

Reallocs:0

Pending Sectors: 2

PowerOn Hours: 1848

Start/Stops: 2825

Temp: Current 19c

Temp: Min 11c

Temp: Max 47c

Tried DFU and the reformat options. Nothing worked.

Unfortunately, I nor anyone I know has access to a Mac. Thanks anyway for your help.
