bsod after login

The crashes which happened after Avast was removed would be interesting to analyse.

I'm also not seeing the obvious link to 2xexplorer. Unless it's injected its own k-mode driver, it's just an app. Doesn't matter if it's as old as the hills - it's just user-mode code. If it did somehow manage to cause a bugcheck, that would constitute a bug in the OS.
you bring up a good point H2SO4
although i havent seen xplorer² load anything in Ring-0 though...
its mostly all user-mode code like you said and the worst i can do is crash itself (well maybe it can do worse things but like you said again it did bsod it would technically be a OS bug (or like i said if it was acessing a network share then it would be a driver issue) as its not running in either Ring 0-2..)
i would actually like to see which update he is talking about as i have a customer with a similiar laptop model and i have not heard any news of any errors (also configured with avast)

I agree with both of you.

It would not be a kernel mode app. "2002" in a 2008/9 SP1 system just looked odd. I do believe it will cross paths with ?? and result in appcrash/ hang soon enough. OP is x86, so it is most likely OK for now. It would be fooled, of course, in x64 virtualized world.

ZoneAlarm not found in stack text, yet I assume it contributed to BSODs based on the 0xc0000005 exceptions found in WERCON. I do think it caused those.

I don't know what would account for the 0x80000003 exception. Unless injection of ???

Hi -

Thank you.

I asked for msinfo32 b/c I like to review the WERCON portion of Software Environment to see appcrashes/ hangs.

WERCON showed this Explorer crash w/ ntdll.dll - but a 0x80000003 exception. To me, that indicates a checked-build. But of what? Both MS modules have the tell-tale SP1 timestamp of Jan 19 2008 and the correct version number for SP1.
Code:
[FONT=lucida console]3/15/2009 1:48 AM       Application Error       Faulting application Explorer.EXE, version 6.0.6001.18000, [/FONT]
[FONT=lucida console]time stamp 0x47918e5d, faulting module ntdll.dll, version 6.0.6001.18000, time stamp 0x4791a7a6, [/FONT]
[FONT=lucida console]exception code [B]0x80000003[/B][/FONT]

So, no - I found no direct 2explorer.exe tie to BSOD - just the 2002 date.

I just noticed while copying the above out, the presence of a BSOD-causing giant -
Code:
[FONT=lucida console][B][SIZE=3][COLOR=red]ZoneAlarm[/COLOR][/SIZE][/B][/FONT]

@ darkassain - un-install ZoneAlarm. Otherwise, you will be back for additional BSODs in the near future.

Regards. . .

@ H2SO4 - I really like your how-to on crash dump analysis.
I refer many to them.

I also agree on not seeing Avast in stack text. The purpose of Driver Verifier.

.
i believe you directing it to jcgriff2 this correct?
because if you are not then im confused....:confused:

im guesing since zonealarm gave a appcrash i believe it would be the injection of the zonealarm firewall kernel driver (which does run in ring-0)
which means that the firewall driver might be the cause of this...

My apologies.

it happens all the time...;)
well it does happen often (at least to me..:p)

Thank you.

I myself only came by 0x8...3 a handful of times during recent BSODs. I have seen many BSODs with the checked-build exception in the past, but most of them turned out to be just that - a checked build of Vista or XP.

The nicest thing anyone said to me all day. Now I feel obligated to go fix it up :)

I can't tell where that hard breakpoint in the OP's Explorer crash is coming from, but I cannot link it to the BSoD at this point. As you said, this looks like a networking SNAFU...

The first local in TdxIssueQueryAddressRequest is a struct with a null member at +0x128. I think that's what leads to the crash, but I'm zonked and mistakes in disassembly are likely :)

If the worker thread crashes the same way in the absence of the Avast filters, ZA, and with an updated NIC driver, this would get really interesting to troubleshoot.
