mat-debug-xxxx.log files

Reinstalling graphics driver will fix this issue, if it didn't reinstall the audio driver, chipset driver and firmware driver will fix it.

It seems like its happening due to unsigned driver.

For more information regarding the fix  you can follow the below guide

Method 1

To uninstall a graphic driver.

In search bar type as “add or remove programs” (without quotes)

Open the result

In it search for **"Nvidia"**if you have Nvidia graphic card and if its AMD graphic card  search for "AMD"

Then uninstall all the results you find there related to the search.

Once uninstalled restart the system and visit your manufacturers website for downloading the available graphic driver for your system

Method 2

In case if you are having "Intel graphics" or you didn't find any results of both AMD and Nvidia you can follow the below guide to uninstall

Right click on the windows icon (Start Menu) 

Select "Device Manager" 

Expand "Display Adapters" 

Right click on each item here 

Select "Uninstall" 

Press the F5 key on your keyboard 

and restart

Method 3

If the above guide didn't work then  reinstall the audio driver, follow the below guide to do so.

1. Press Windows key + X and select device manager.
2. Locate the audio driver and right click on it and select uninstall

(there will be two results of the audio driver which is "Audio input and sounds" and "sound video and game controller" uninstall the audio driver from both of the results,  it will also ask you to "delete this driver" put a tick mark on the check box if asked)

3. visit the manufacturer for installation of audio driver

Method 4

If the previous methods didn't help  then  install all the chipset drivers and firmware driverspresent in the manufacture's website.

Method 5

Even by executing all the above guide if the issue is still the same then you can follow the  below method (which is to update all drivers in device manager)

To update all the divers -

Press Windows key + X and select device manager.

 Then select Device Manager.

Select all category one by one (you can double click on the category to expand if you are not seeing the option "update driver")  then right-click and

No. I do not have those programs installed on this laptop. I also disabled Smartbyte telemetry service (although it reappeared in my tasklist after doing so). However the mat-debug-xxxxxx.log files are still propagating (every 5-15 minutes) as zero byte files in my temp folder.

I uninstalled Microsoft One Drive and the mat-debug-xxxxxx.log file is still propagating in my temp file.  I am going to ask Dell if they understand what a mat-debug-xxxxxx.log file does.

Is there a way to re-install it later? Also, after watching what is going on using Process Explorer, I think the real culprit may be Smartbyte telemetry used by DELL (my computer is a Dell Inspiron I5 series). It gave me problems some time back when it was filling up my Windows/temp file with telemetry files.  Is that possible?

I disabled it but the "mat-debug" (and to a lesser extent "aria-debug") files continue to propagate in my temp folder. Should I uninstall One Drive? (I don't use it).
