Blue screen: aswtdi.sys

[sparky_132]

Hi,

New laptop has been crashing occasionally at random (64-bit WIndows 7). I ran WhoCrashed which gave the following:

On Mon 5/16/2011 6:16:23 PM GMT your computer crashed
crash dump file: C:\Windows\memory.dmp
This was probably caused by the following module: aswtdi.sys (aswTdi+0x11A8)
Bugcheck code: 0x7F (0x8, 0x80050031, 0x6F8, 0xFFFFF80002C92FC0)
Error: UNEXPECTED_KERNEL_MODE_TRAP
file path: C:\Windows\system32\drivers\aswtdi.sys
product: avast! Antivirus System
company: AVAST Software
description: avast! TDI Filter Driver
Bug check description: This bug check indicates that the Intel CPU generated a trap and the kernel failed to catch this trap.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: aswtdi.sys (avast! TDI Filter Driver, AVAST Software).

Avast version 6.0.1289.

The zipped dump (144MB) can be found here: http://www.sendspace.com/file/opwa2l

Please investigate.

Thanks.

Thanks, this is a compatibility problem between Windows/avast/ZoneAlarm, sometimes it may lead to a BSOD. We'll drop aswTdi.sys using in avast7, but we can't fix it in avast6 version.

However, your memory.dmp file was created on Mon 5/16/2011, it's quite old -- do you have any other latest minidumps? (\Windows\minidump folder?)

Thanks for replying and acknowledging that it is an issue.

What's the release date for Avast 7?

Or you could drop ZA . Avast 7 ? Some time during 2012.

In any case, I don't think your memory dump was created while using Avast 6.0.1289, because of the date. So, maybe you are not having BSODs with the current 6.0.1289 version?

Yeah you're right, it probably was an earlier version of Avast back in May, but unfortunately it did crash last week, although I can't find the memory dump.

Interesting that the bug also involves ZoneAlaram - I think I'll change firewalls until Avast 7 is released.

Thanks.
