Norton background tasks while computer is idle affect iphone connected via usb?

Sometimes when my computer is idle Norton does background tasks such as quick scans, disk optimization, etc. I was wondering if my iphone is connected to itunes and the computer via USB charging, will Norton's background tasks affect the files (music, pictures, videos, apps, etc) on my iphone or the device itself in general?

If Norton is performing a disk optimization while my iphone is connected will any files on my iphone be optimized as well?
