    Yes, happned in Firefox and also in Chrome too. I would suggest temporarily uninstall Avira to see if problem still occurs. Anti Virus software known to cause BSOD's.

    While testing, use Windows Defender and the Windows Firewall to keep from being infected .

    FYI, I did look at the dump files and that's what they all pointed to Firefox and Chrome and Netio.sys was the cause. the dmp files only give you a glue of what happened, it does not tell you exactly where the problem is.

    Now, we've already suggested you what to do to isolate the problem so did you do it ?

    Also, Anti Virus software is hard to uninstall, you need to use their uninstaller to do it.

    I uninstalled the avira and now using windows defender only and the blue screen didn't show up since then, I think it might be solved now

I have had this problem before but only once and I did not pay heed to it. I download torrent quite a lot using bittorrent, and bsod has never occurred. But ever since this last torrent I have been downloading it has been happening quite often and only whenbittorretn is active. - - - - -
