NIS 2011 automatically disabled after ~10 minutes!

Everything was fine until today...

 

I'm not sure if it was due to a recent update (do mine automatically), but my NIS 2011 automatically disables everything after about ~10 minutes.

 

I have to restart the computer every time for my NIS to return back to normal.

 

The system is 100% virus / malware free, and I also use Spyware Doctor as another malware scanning program.

 

The History log shows this:

Error ID = 1

Module ID = 3052

Error Code = 0x80047813

Product Version = 18.6.0.29

Product Name = Norton Internet Security

Error Description = "NIS has encountered an internal program error

 

Lastly, whenever I try to shutdown my system... one of my SVCHOST.EXE files hangs forever, and I have to manually terminate it... this never happened before either.

 

The description is:

Action = Unauthorized access blocked (Access Thread Data

Target = NIS 2011 / Engine / 18.6.0.29 / cltmh.exe

Actor PID = 1132

Target PID = 2236 / 2468 / 1384 / 1348

 

Does anyone have any idea what might be going on here?

Again, this just randomly started to happen today.

 

Oh... and if you're wondering, I always run my system from a Limited User Account.

My Admin / Norton Settings are both password locked.

 

Thanks.
