Can't access Unknown File 3D54E740.TMP

The info below is from "File Insight" after a full system scan of my Win7 system.

 

I have gotten a small "file unknown" (or similar) popup window periodically for the past couple of days.  I tried to navigate, via CMD, to the file, but "access denied" to the SrtETmp subdirectory.

 

This is definitely not something that I knowingly downloaded.  What is it & how do I delete it?

Full Path: c:\ProgramData\Norton\{0C55C096-0F1D-4F28-AAA2-85EF591126E7}\SRTSP\SrtETmp\3D54E740.TMP
