I'm skeptical ESET or the other AV platforms generate these.  I think Lacerte is generating these as:

1 - the first word is Lacerte

2 - the half dozen or so that I have at least 3 different AVs and are identical formats.

3 - Most, but not the latest, are in the Lacerte folders

I just did a search of my Lacerte folders and found an orphan URN file and some others Lacerte files  from that date and time.  I'm going to assume Lacerte crashed or at least error-ed (What else is new)
