BSOD (0x8e) By Mpfltr.sys

» In my PC I have 2 hdd (SATA & IDE). In SATA I have installed 2008R2 and in IDE Win 7. Both the OS is giving BSOD several times and error code is 0x8e (in all the BSODs). I found mpfltr.sys in WinDbg (not 100% sure) as MS essential is installed in both OS. I do not suspect it as hardware issue because there is no particular trend.

» Mpfltr.sys is a Microsoft Windows Malware protection system driver file. Some malwares camouflage themselves as Mpfltr.sys. If you are able to locate the Mpfltr.sys in some other strange location on your system for example in c:\windows or c:\windows\system32 folder, or it exists in the form of multiple files, it is an indication that your system has a spyware infection(Exploit:Java/CVE-2012-0507). You will have to scan and remove the software by using an antispyware in safe mode.

After that, download DLL Suite, install and reboot the computer in safe mode: press the F8 key before the Windows screen appears. This will boot the computer into the Advanced Options screen where you can choose advanced boot options. Choose "Safe Mode" and press "Enter", wait for the Windows screen to appear, then click DLL Suite’s Dashboard menu > Click Scan DLL Errors button > Click Fix DLL Errors button after the scan, and the blue screen will be repaired automatically, just because DLL Suite has built-in feature of Fix BSOD. What’s more, not only the direct cause for the blue screen of death has been removed, but also other out-of-date or corrupted dll file, which are the potential causes of BSOD, are repaired this way.

    This is probably causing your error.

    Minimum system requirements for running Microsoft Security Essentials

    Operating System: Windows XP Service Pack 3 (SP3)*; Windows Vista (Service Pack 1, or Service Pack 2)*; Windows 7.

    Try uninstalling MSE and see if the problem goes away.

    More over Windows 7 Ult is also showing the same bug check code.

    Why the issue is occurring now? Two days back I uninstalled and installed it back and it did not prompt my warning or alart reagrding that.

  3. ALISON GLEESON replied on March 22, 2013: » I would suggest you to run System File Check (SFC) scans and checks if it helps. System File Checker gives an administrator the ability to scan all protected files to verify their versions. If System File Checker discovers that a protected file has been overwritten, it retrieves the correct version of the file from the cache folder (%Systemroot%\System32\Dllcache) or the Windows installation source files, and then replaces the incorrect file. System File Checker also checks and repopulates the cache folder.
