Problem with Norton Antivirus 2004

NTFSD
1

Hi all,

I have created a virtual disk. After I have created a disk and
trying to format the disk Norton Antivirus 2004 crashes.
I have no problems without Norton installed.

The memory dump says:
BugCheck C4, {90, ffdff120, 0, 0}
Probably caused by : SAVRT.SYS ( SAVRT+36860 )

Sometimes it is NavEx15.Sys that crashes with C4, 90.

To refresh you memory is C4
DRIVER_VERIFIER_DETECTED_VIOLATION (c4)
and 90
Arg1: 00000090, A driver switched stacks. The current stack is neither a
thread
stack nor a DPC stack. Typically the driver doing this should be
on the stack obtained from `kb’ command.

Have anyone of you any qlue how you can work around this problem?

Regards,
Daniel Öberg

According to WinDDK, this bugcheck means
that a driver has switched the stack (which is exactly
what Symantec antivirus does).

Turn off the driver verifier for NAV is my only
hint to solve the problem.

The solution is to turn off deadlock detection in Driver Verifier if NAV is
on the system.

Yes, Norton is notorious for doing this. It is very illegal to switch stacks
in kernel mode.
