All these .SLG files?

I've noticed that I have over 5000 .SLG files, some are 485 bytes and some 956 bytes in the "C:\ProgramData\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7}\NSBU_22.0.0.110\Backup\CATALOGFETCH" folder.  I've read that they may be some type of log file but not sure.  Some times there are 4 to 5 per day.  Now I know that really doesn't add up to a lot of disk space these days but 5000!  I would like to delete them if possible. Anybody know if they are really needed?  Is there a way to turn these off, maybe in the Registry?
