I am facing some problems regarding installation of Norton Corporate
7.51.847 and our filter driver on windows 2000. If I install Norton
7.51.847 and then install our filter driver, the m/c goes
into a loop and continuously reboots. I have to uninstall our driver after
starting the system in safe mode. On the other hand, if I install our
driver first and then try to install Norton Corporate 7.51.847 then there
is a message that “Norton Realtime protection failed”.
It means the antivirus protection failed to start, right ? There is some
clash betn our device driver and the driver installed by Norton. Can
anyone please give me some suggestions to avoid the clash ? This problem
doesn’t occur on Windows NT though. We are running the same filter driver
on Windows NT and Windows 2000.

Subodh there are many things which could cause incompatibilities between
your filter driver and the one in nav. Couple of questions …
- You say the machine goes into a reboot cycle. How far does it get in
the boot before it reboots?
- You say its fine on NT4. Does that mean with your filter driver and nav
at the same time?
This could happen since either filter driver could be making
certain assumptions about thread context or reentrancy issues that
the other isn’t aware of.
You could try loading your driver programmatically instead of automatic
and then trace through a file access and see if you can determine the
cause of the clash.

If the kit keeps restarting (rebooting) it sounds like it could be triple
fault. Just one possibilty.

Check carefully for stack usage. Norton is a bit stack hungry!

Do you how any raw values for this? Such as 1K, 2K…?

Well, system just keeps on rebooting, never starts. I had to uninstall
driver from safe mode. The clash betn Norton and our driver wasn’t that
bad initially. It increased after we made one change in the code.
Earlier, for each change in the monitored folder, the driver used to open
log file, write record and then close it - too much file i/o. So the
driver used to crash when changes were made in the monitored folder
automatically thro’ a script. So we kept the log file open to save
file i/o time. The driver never crashed then but there was problem with
Norton as I mentioned. Is this open file causing all the problems ?
Practically, this looks like the source of problem as we have not done any
other change. Can you throw some light ? Surprisingly, there is no
problem on NT, only on 2000.
After taking a new 2000 m/c now I find that system works well if Norton is
installed after filter driver and compiler option is changed to ‘maximize
spped’. I got a mail which listed a similar problem.
I had a similar problem with a program I wrote. When Norton virus scanned
it, it rebooted the computer. I ended up just throwing some classes into
my project that I never used. This changed the structure to the .exe and
Norton no longer restarts the computer …
Can it be true ?

Dejan,
I don’t have the values - it wasn’t me that looked at this problem. I’m
just going on 2nd hand info. (which of course means for you it’s 3rd
hand!) IRC they monitor the stack usage and stack swap when they are
gettin glow. However the algorithm for doing this isn’t too reliable,
and they don’t do it on all paths.
Sorry
Andy
