Win XP BSOD from SYMEFA.SYS

I have the same problem as bcotter, I tried to solve the problem with the support but after uninstalling and reinstalling the program the problem is always there. My opinion is that the BSOD from symefa starts with the starting of  manual silent activity of Norton when the system is Idle furthermore the problem has started with the upgrade tothe last version of Norton Internet Security. I think the development team of Norton should resolve this problem as soon as possible.
