As a side note.
NPE is not designed as a regular scan item. You should be using your regular Norton product Full System Scans for your regular protection.
NPE is designed as a Repair Tool if you think your regular scans have missed something.
Unless you suspect there is an infection that normal scans missed, you should not be running NPE. The problem is that as aggressive as the NPE scan is, there is a risk of false positives being detected. If you do not understand what the files are that NPE wants to remove, you could actually make your system unbootable.
