BSOD Bad Pool Header - malwarebytes web access control (mwac.sys)


Recommended Posts

Hi

 

I am also getting many BSOD crashes over the last week since I have reloaded Windows 10 and have updated everything. I am using the WhoCrashed software (home edition v5.5.1) and have attached the report for that. I have also attached the report (zip file) from another BSOD program previously been used on this webpage.

 

It is pointing towards the web access control file (mwac.sys).

 

Please help.

Regards

I'm pushing against the experts here, but I believe that MalwareBytes and your antivirus are conflicting.

The common belief is that since MalwareBytes isn't an antivirus, it won't conflict with your antivirus.

The test here is to disable one of them from loading with Windows and see if that stops the BSOD's

 

But beyond that, here's the formal analysis:

 

Your UEFI/BIOS (version 1203) dates from 2015.  Please check at the manufacturer's website to see if there are any UEFI/BIOS updates available for your system.  This is just in case there has been a recent update.

Only 3 Windows Update hotfixes installed.  Most build 10586 (TH2/1511) systems have more than this.  Please visit Windows Update and get ALL available Windows Updates.

You have a NETGEAR A6200 USB WiFi Adapter:

I do not recommend using wireless USB network devices.
These wireless USB devices have many issues with Win7 and later systems - using older drivers with them is almost certain to cause a BSOD.
Should you want to keep using these devices, be sure to have the latest W7/8/8.1/10 drivers - DO NOT use older drivers!!!
An installable wireless PCI/PCIe card that's plugged into your motherboard is much more robust, reliable, and powerful.


K: drive has less than 1% free space.  Windows likes 15% free space in order to perform stuff "behind the scenes" without adversely affecting the system's performance.  Please free up 15% on ALL hard drives (you can get away with 10% on larger drives and won't notice a large performance penalty)

You have 8 listed hard drives.  What is the make/model/wattage and age of your Power Supply?

These devices have problems in Device Manager:

 

Realtek PCIe GBE Family Controller    PCI\VEN_10EC&DEV_8168&SUBSYS_86771043&REV_15\4&1020E6D3&0&00E7    This device is disabled.
Viscosity Virtual Adapter V9.1    ROOT\NET\0000    This device is disabled.
Intel® Ethernet Connection (2) I219-V    PCI\VEN_8086&DEV_15B8&SUBSYS_86721043&REV_31\3&11583659&0&FE    This device is disabled.

Please enable each one of these devices and then update their drivers.

Once that's done, feel free to disable the device if that's what you want.

 

Daemon Tools (and Alcohol % software) are known to cause BSOD's on some Windows systems (mostly due to the sptd.sys driver, although I have seen both dtsoftbus01.sys and dtscsibus.sys blamed on several occasions).

Please un-install the program, then use the following free tool to ensure that the troublesome sptd.sys driver is removed from your system (pick the 32 or 64 bit system depending on your system's configuration):  New link (15 Aug 2012):  http://www.duplexsecure.com/downloads(pick the appropriate version for your system and select "Un-install" when you run it).
Alternate link:  http://www.disc-tools.com/download/sptd
Manual procedure here:  http://daemonpro-help.com/en/problems_and_solutions/registry_and_sptd_problems.html
NOTE:  The uninstaller may not find the SPTD.sys driver.  Don't worry about it, just let us know in your post.

You have MalwareBytes and BitDefender 2016.  If you look at the other topics here, you'll find quite a few mentions of problems between these 2 programs.
Some posters have suggested fixes - either disabling things in BitDefender, or reverting to BitDefender 2015.

I'd suggest that you first stop MalwareBytes from loading with Windows - and see if that stops the BSOD's.

 

Please uninstall the Western Digital software also.  The wdcsam64.sys driver (the 2008 version) is known to cause BSOD's on some Windows systems.
