Suspicious Statistical Submission entries in NIS history

Hello. This morning, I noticed a group of files pending being sent to Norton through Statistical Submission. I did some snooping around and they appear to connected to C:\Windows\Fonts. Here's what they are.

 

hornb_ttf.

horni_ttf.

hangeb_ttf.

hangez_ttf.

beachexb.ttf

hornz_ttf.

hornr_ttf.

 

I've never seen it submit anything like this before. Is there a problem here or is this normal? Thanks.
