I suspect that there is a conflict between the loading of Norton
AntiVirus AutoProtect and another driver on your system. These
problems can occur if both drivers are attempting to load
simultaneously. The following document explains how to troubleshoot
these types of problems:

It is also possible that there is a problem specific to the Norton
AntiVirus Symevnt drivers. Use the following instructions to update
these to the most current version:
Symevnt Version 10.2.13.1 Update

This problem could also be related to low system resources. Please
review the following instructions to increase system performance:
