There are two KB articles I found that may be relevant here:

0x000000FC (ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY):

* http://support.microsoft.com/default.aspx?kbid=878474

and how to really disable antivirus software:

* http://support.microsoft.com/default.aspx?scid=kb;en-us;240309

In my opinion, there are four possible causes here (at least):

1) It's a Norton Antivirus problem.

Be sure to update your Antivirus software to a recent version.
A possible way to comprove this would be to remove the colinux driver
and see if this error is still triggered.

2) Norton Antivirus doesn't cope well with colinux driver.

It may be that Norton AV doesn't work well with colinux, resulting
in the stop error mentioned.
It can be comproved by completely uninstalling Norton AV and checking if
colinux runs OK (and don't forget to follow the link to make sure NAV is
really uninstalled).

3) It's colinux.sys fault. It's still not ready for DEP/NX.

I don't believe this, as if it was, it should be pointing into the
colinux.sys driver, not naveng.sys (Norton AV driver).
With this I mean it can still have problems with NX, but I don't
believe the cause of the current problem is colinux, but maybe 2).

4) Other problems, like a real virus in your PC.

You could have a real virus in your PC, trying to disable the Norton AV
program, resulting in that exception with DEP/NX enabled.
As NAV is very used program, there are many viruses that try to disable
it first, and can be failing now with DEP/NX enabled.
A way to confirm this is using some other antivirus, like AVG, Avast,
etc (they have a free edition for home use).
