Nsstream.sys BSOD (blue screen of death) with Panda and Battle.net client
Recently I installed for the first time windows 8.1 and Panda antivirus. Everything was running ok until battle.net client was installed and it was necessary to update installed Blizzard applications.
As soon battle.net update would be started or continued, Windows would crash/BSOD (blue screen of death) with memory page fault, naming Nsstream.sys as faulty module.
After some investigation, thanks to Panda forums, i found root cause for this problem – it is bug in Panda antivirus or more precise, in their “Monitor the URLs accessed by each process” option.
To workaround this problem, it is necessary to turn off this option until patch is provided with new Panda AV version.
Steps:
- Start Panda AV client
- Click on menu icon and select settings
- Select Process monitor option
- Set to OFF Monitor the URLs accessed by each process option

Sorry to hear that Kristoffer. I have no issues since this change. You can try to stop Panda virus monitoring completely or deinstall the Panda, restart computer and try the Battle.net update. If issue continues then your problem might be caused by something else and not Panda AV.

Wow, thanks a ton for this post. I ran into this same problem and would never have suspected Panda as the root cause.
After uninstalling Panda, battle.net runs smoothly.
Thanks again. You saved the LAN Party on last weekend 🙂
