I'm running windows 10 build 14393.447

The windows upgrade was done some time ago. I've been on windows 10 since it was first available.Malware bytes are also been on the PC for well over a year and they have both been updating with software updates as they become available.

If your Windows is on the current branch release  ( 14393) then there likely are other issues/sources of friction on this system.

I suggest you run FRST diagnostic reports and attach.  And know I will likely move your thread over to the BSOD-crash help area.

Please download    Farbar Recovery Scan Tool and save it to your desktop.

You may wind up needing to temporarily turn off your antivirus program IF it interferes with the diagnostic tool-reports listed below.

Right-click on *FRST* icon and select  *Run as Administrator * to start the tool , and reply *YES* to allow it to proceed and run.
_Windows 8 or 10 users will be prompted about Windows *SmartScreen protection* - click line  *More info* information on that screen and click button *Run anyway* on next screen._
Click YES when prompted by Windows U A C prompt to allow it to run.


Approve the Windows’ UAC prompt on Windows Vista and newer operating systems by clicking on Continue or Yes.

Click Yes when the* disclaimer* appears in FRST.
The tool may want to update itself - in that case you'll be prompted when the update is completed and ready to use.

Press Scan button.
It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
The first time the tool is run, it also makes another log (Addition.txt).
Please attach FRST.txt & Addition.txt along your next reply.


This tool will collect some information on the installation of Malwarebytes and create a report I need to review:

NOTE: You may need to temporarily turn off your antivirus if it interferes with this tool.

Download mbam-check.exe and save it to your desktop    "from this link

Right-click on *mbam-check-* & select Run as Administrator & allow to Run when prompted by User Account Control.

Do have patience while the tool runs.  It may take a while, and will flash a command prompt window.  And then it will start your text editor ( default is typically NOTEPAD).

It should then open a log file CheckResults.txt.  Just do a File >> Exit in NOTEPAD.
You should attach the *CheckResults.txt* file located on _*your desktop*_ so that I can review.
