BSOD and aswTdi.sys

Avast Free Antivirus / Premium Security
1

Hello

I’ve been using Avast for years and it worked fine. On Christmas I upgraded my old computer, almost everything is new now, it’s Celeron E3200 2.4 GHz, 1 GB RAM, board GA-73PVM-S2H. I installed new system, Windows XP SP3, and latest Avast 4. Then the crashes started (bsod). It happened a few times. It happens randomly, usually (but not always) when I’m browsing the internet, just after I click a link. I upgraded avast to version 5.0.418, but I’ve just got blue screen again.

The blue screen says something about tcpip.sys and windows debugger complains about aswTdi.SYS. I have a full memory dump. I’m uploading the dump to ftp://ftp.avast.com/incoming to karols-aswtdi-bsod-Memory022610-01.zip

About my network software - I use Firefox 3.5.8 and MetaProducts Net Activity Diagram. No P2P software running, no third party firewall, no other antivirus, antispy etc.

I searched this forum and asked google and it seems that it really was a bug in aswTdi.sys, but I don’t know if it is fixed in version 5.

Do you know how to fix this problem? It’s getting annoying but I don’t want to change my antivirus program.

Hello, thanks for your dump - the crash was caused by Net Activity Diagram application. We can’t do anything about it, because avast drivers were not involved in the crash.

Thanks for debugging. In the meantime I disabled most of Avast modules and even removed aswTdi.sys file (don’t worry, I have a copy :)), but crashes continued. Net Activity Diagram was my second suspect. I uninstalled Net Activity Diagram and I’ll wait and see.
