    BAD_POOL_HEADER caused by ntoskrnl.exe and tcpip.sys


    Hello,

    I have Windows 10 PRO installed. Other important installed applications are Malwarebytes (Antimalware and Antiexploit), Adguard and utorrent.

    Last night I have started a big download on utorrent (a 20GB file) and after some minutes I got this BSOD with BAD_POOL_HEADER; the system restarted, and again after some time I got again BSOD. Again and again, for a total of 6 BSODs. After that, I disabled utorrent and both Malwarebytes programs, and since then I have had no crash.

    Could you please tell me what is the problem, by looking at the log archive I am uploading, and what should I do to prevent this BSOD (a solution not involving permanently disable of Malwarebytes and utorrent)? If you have any more questions for me, please ask!

    Also, I will upload an image taken with BlueScreenView application:
    Attachment 32569

    Thanks in advance!

    EDIT: since problem involves TCP/IP, I think I should mention that I use wireless USB (as I am on a computer), with drivers installed from the same USB, and the site for this USB device is http://www.tenda.cn/uk/product/W326U.html

    Are you running MalwareBytes realtime? There are plenty of instances of it showing in your logs.

    Code:

    If so, just run MBAM on demand to see if the problem stops.

    Yes, when I had those BSODs, I was running Malwarebytes realtime. Now, I have disabled it, as a temporary solution, and no crash occured since then (it appears utorrent was not a problem).

    Ok, I ran a demand scan, and everything was ok. I even reactivated Malwarebytes Antimalware (but uninstalled AntiExploit), and so far I had no problem.
    I suspect the problem appears only when I am downloading a huge file with utorrent (and Malwarebytes is realtime) and the download speed goes high (probably around 4-6 MB/s). I will try tonight to check if this is true.

    A week ago one more guy had the same Error. You are right Malware bytes may be the Culprit. The Drivers conflicts on boot causing the issue. I learned it Here Fix "Bad_Pool_Header" Error in Windows 7/8/8.1 & 10 | Fix Errors

    If the Issue persists again and again even after disabling Malwarebyte or any other Anti virus other then Windows Defender then you might want to make use of Restore point. Obviously if you had already created it. Hope this helps.

    Today I started again to download a big file, and everything seemed ok. But, after I entered on the site http://www.gq.com/story/scariest-horror-movies-ever and scrolled for some seconds, the BAD_POOL_HEADER BSOD appeared again. After the restart, I disabled malwarebytes, restarted the download on utorrent, and everything was ok. I again entered this site, and forced some scrolling (very fast scrolling up-down from the head to the bottom of the page) and nothing happened.

    So, it appears malwarebytes has an issue with high speed downloads and/or scrolling on sites with much graphic content. I will disable it for now and only run on-demand scans.
