Wal files being created on C: drive

Hello,

I have noticed on my C: drive that I am getting wal files with a string of numbers being created (see below). These files are completely empty. A moderator in the MS Forum said they are coming from Norton specifically nuPerfScan.exe. Is this suppose to happen and can I stop these files from being created and put on my C: drive and also can I delete these files.

Respectfully,

Don
