Windows 10: Constant BSOD - BAD_POOL_CALLER/HEADER Solved

    Constant BSOD - BAD_POOL_CALLER/HEADER


    I've been getting this BSOD for quite a while now, I've re-seated my RAM, lowered my CPU overclock back to stock, updated my drivers and removed my killer network driver and replaced it with a more stable one. Pretty much ran out of options on my end & find this pretty difficult to fix as I've never had such problem with my other computers I've built before. Thanks in advance!

    The latest dump indicates a problem with mwac.sys which belongs to Malwarebytes Anti-malware.

    Code:
    *** WARNING: Unable to verify timestamp for mwac.sys
    *** ERROR: Module load completed but symbols could not be loaded for mwac.sys
    What anti-virus are you using? If it's BitDefender, see here: BSOD - BSOD, Crashes, Kernel Debugging - Malwarebytes Forums, see if that resolves the problem.

    If not, uninstall Malwarebytes Anti-malware following Maurice's instructions here: BSOD - BSOD, Crashes, Kernel Debugging - Malwarebytes Forums

    One of the "fixes" I found online was doing that, when I saw it wasn't successful I didn't know how to revert the change.
    Thanks so much for the mwac.sys fix! I really appreciate it, you're a life saver!
