This has been asked before, but when I quickly checked I didn’t find an answer that clears this up.
So, on Windows 11, Norton creates .WAL - files on C: directory. Those are 0 bytes long.
What are they? Is it safe to delete them? Why it generates them? I have not noticed it before, so is it a bug or a feature.
Thank you.
Norton v22 or v24?
Did you try refreshing/reinstalling your Norton?
Do you run Norton SmartScan?
Norton’s component “nuPerfScan.exe” seems to be creating those files.
try renaming nuPerfScan.exe … for example: nuPerfScan.exe123
Please post progress
OK, I will try that. Thank you. 
Sorry…my WAL files 0 bytes content from old Community is Oops!
It seems I am unable to rename nuperfscan.exe , it won’t let me do that even when I login as admin and disable real time protection etc.
But it is ok, I suppose they will fix this eventually, until that I will just delete those files, don’t suppose there’s harm in that.
my bad… I neglected to mention Product Tamper Protection = temporary turn off
OK, works now. I ran a smart scan and didn’t get any new WAL files.
Thank you 
First access with this community. [date=2024-09-29 time=05:45:00 timezone=“Europe/Brussels”]I see two files with “same” name but with 2 cases difference. Viewable in Paramètres of Windows 10.x.y.z : one with Icon Norton and the other with icon who seem’s to be a Windows icon ( nuPerfScan.exe AND nuperfscan.exe ). The “same” name of file is a little bit a problem of viruse or not ???
Hello @Marc_Absil
are you finding … nuPerfScan.exe and nuperfscan.exe?
as I recall…with my N360 v22 = nuPerfScan.exe
for example: https://processchecker.com/file/nuPerfScan.exe.html
and for reference: related “empty wal files” pics [here]
Note: with my N360 v24. I’m not finding nuPerfScan.exe
Hi,
Could you please update to the latest version Norton Security 22.24.8.36 for Windows is now available! and let us know if this has been fixed? Thank you.
@Don54 could you too please check?

It looks as if it has been fixed so far. If I see them again I will let you know.
Respectfully,
I’m still seeing these files being generated on my C drive as of December 1st. I’m on version 22.24.8.36.
Confirmed same results on W7 as well.
