Avast Causes BSOD in Windows 8 [Fix]

Are you getting BSOD with Avast in Windows 8? here is the fix. If you’re using Avast latest  version 7.0.1474 in Windows 8 and getting Blue Screen of Death first let me tell you’re not alone and second Avast is working on a fix meanwhile suggesting users to either turn off network shield or apply the patch provided by them temporarily until they address it in the next update. This patch applied ‘will invalidate it self with new program update’.

It seems as if Avast system drivers are culprit for BSOD. If you’re sure Avast causing the issue do either of two things mentioned below.

1. Disable Network driver: Open Avast user interface>Real-Time Shields>select Network Shield and on-right side click on Stop button and select “Stop for permanently”.

2. Apply the patch by Avast to prevent BSOD

This patch is for aswNet.sys, BlueScreen in NETIO.SYS on Windows 8. Before applying he patch you first need to disable Avast self defense module, for that

  • Open Settings>Troubleshooting>uncheck for ‘Enable Avast  Self-defense module”
  • Download 32 bit or 64-bit package and extract to C:\Windows\System32\drivers folder (here is C: is windows 8 installed drive)
  • Enable Self-defense module and restart your Computer.

Meanwhile Avast got Windows 8 compatible logo from Microsoft and seems that has nothing do with BSOD. To play safe I recommend you to apply the patch than disabling the network shield.

Have you experienced BSOD in Windows 8 due to Avast? share with us in comments.

I trust Avast as my anti-virus solution, just because MSE freezes system when I access folders with many EXE files. I’m currently using Windows 7 in my computer with Avast installed.

FYI Windows 7 is not affected with this.

Thank you for the temporary fix! Seems every time I ran uTorrent application the BSOD would occur but since I was able to run computer without errors before I installed Avast, it was obvious where the issue came from at least.

Are you blue screen with Avast?
If so

Download 32 bit or 64-bit package and extract to C:\Windows\System32\drivers folder (here is C: is windows 8 installed drive)

please follow the steps mentioned in the article.


Julien Lamy January 14, 2013 at 3:55 pm

No, the problem has still not been solved.


Venkat January 14, 2013 at 4:17 pm

Yes you’re right we realized it later, Avast still not released new program update as it still stuck on 7.0.1474, am i right? Are you guys finding it difficult to apply the patch?


Julien Lamy January 14, 2013 at 6:41 pm

Well, applying the patch is not difficult. Having the patch make any difference is… I still get BSOD.

Maybe it’s juste because I didn’t deactivate Self-defense, I’ll try again tonight. But because of this I already have lost quite a lot of time…


Jaroslav February 21, 2013 at 8:24 pm

Problem still persists.


Venkat eswarlu February 21, 2013 at 8:42 pm

Yes Avast is aware of that, try disabling network shield or apply the patch, or you could try Avast 8 RC1 which not got any noticeable issues on Windows 8.
