Windows problem report saying that NAV is causing an unexpected shutdown

For over a month now windows problem reports and solutions has been saying that NAV is causing and unexpected shutdown.  The shutdown happens at anytime and every time the machine reboots it says that the problem is caused by my antivirius softwareI have repeatedly followed their steps to no solution and am getting tired of this. If you could please see if you can find the problem I would really appreciate it.  problem reporting.jpg
