Strange statistical submissions of personal pdf files and WindowsFonts files

Good evening,

Upon completing a routine full system scan I took a little gander at my history and noticed a few hundred entries of statistical submissions. I do understand they are sending information back to norton to reduce false positives. However, upon looking at the entries I noticed they were either .tff files of WindowsFonts and also multiple submissions where actually my own personnal pdf files. Is this something to worry about? Or is this because the signatures are picking something up with Adobe flash. 

Some clarifications would greatly be appreciated.

Thanks,

 

Will
