mwac.sys causing BSOD (BAD_POOL_CALLER)

Recommended Posts

I'm constantly getting BSODs with the error BAD_POOL_CALLER. It usually happens when I start up my computer and open Chrome. I ran WhoCrashed and it's telling me that it's probably caused by mwac.sys and ntoskrnl.exe.

mb-check-results.zip

If you haven't done so already, please run these two tools and then attach the logs in your next reply:

NOTE: The tools and the information obtained is safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  • Farbar Recovery Scan Tool (FRST)
    1. Download FRST and save it to your desktop
      Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit
    2. Double-click to run FRST and when the tool opens click "Yes" to the disclaimer
    3. Press the "Scan" button
    4. This will produce two files in the same location (directory) as FRST: FRST.txt and Addition.txt
      • Leave the log files in the current location, they will be automatically collected by mb-check once you complete the next set of instructions
  • MB-Check
    1. Download MB-Check and save to your desktop
    2. Double-click to run MB-Check and within a few second the command window will open, press "Enter" to accept the EULA then click "OK" 
    3. This will produce one log file on your desktop: mb-check-results.zip
      • This file will include the FRST logs generated from the previous set of instructions
      • Attach this file to your forum post by clicking on the "Drag files here to attach, or choose files..." or simply drag the file to the attachment area

One of our experts will be able to assist you shortly.

So it just crashed again with the same BSOD error code. Same as before, turned on my computer after not using it for more than 12 hours, opened chrome and it crashed. When it restarted my usb keyboard wouldn't work but my mouse would work, so I restarted it again and now everything is ok.

Regarding PIA, I would only connect to it when I need to use the VPN, otherwise it remains off. It doesn't connect on startup and I'm using their client.

Can you please zip up the file at C:\WINDOWS\MEMORY.DMP and upload it here? If it's too large to attach, you can use wetransfer.com to send the file to me at dcollins@malwarebytes.com

It seems like the problem has gone away. Turns out my BitDefender was having some issues with updating and that was somehow affecting my system. After I fixed that everything seems to be working normally.

Thanks everyone for the help!
