Norton is not detecting what is in the file,
but what is not in the file. ("reputation")
This is because the file is new.
You can read a full description by "Norton" here...

====
After removing the file from quarantine,
I 'right-clicked on the file', and 'scanned it' with N.A.V.
"On-Demand Scan" = "No Threats Found".
(also scanned good, with "MicroSoft Security Essentials".)
