Bug check description:
This indicates that a pool header is corrupt.

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: mwac.sys (Malwarebytes Web Access Control, Malwarebytes Corporation).

How can i fix this guys?

Hello @gmaister22 and :welcome:

Please try the following.

1. Fully uninstall Bitdefender 2016 Total Security via the Control Panel, Add/Remove

2. Then download and run the following Bitdefender removal tool


3. Then reboot the computer. Then follow the directions below to do a clean removal of MBAM but do not reinstall just yet.

 MBAM Clean Removal Process 2x

4. After you've removed MBAM using those directions then run the following temp file cleaner.


Please Run TFC by OldTimer to clear temporary files:

  • Download TFC from here and save it to your desktop.
  • http://www.geekstogo.com/forum/files/file/187-tfc-temp-file-cleaner-by-oldtimer/
  • Close any open programs and Internet browsers.
  • Double click TFC.exe to run it on XP (for Vista and Windows 7 right click and choose "Run as administrator") and once it opens click on the Start button on the lower left of the program to allow it to begin cleaning.
  • Please be patient as clearing out temp files may take a while.
  • Once it completes you may be prompted to restart your computer, please do so.
  • Once it's finished you may delete TFC.exe from your desktop or save it for later use for the cleaning of temporary files.


Restart the computer one more time.

Then reinstall Bitdefender 2016 Total Security, check for updates. Then do a system scan. Then reboot the computer one more time now.

At this point go ahead and reinstall MBAM again and update it and activate it. Then do a Threat Scan.

You can download the latest version from this link



Let us know if you're still getting a BSOD or not.
