WS.Reputation.1 is a generic detection. . it means Sonar / Download Insight was unable to verify the software publisher against its own knowledge base.
It means that it has not seen very many people with Norton or Symantec Endpoint Protection Download it and it is still unsure how to score it. IE bad or good. the more that people with Norton or Symantec Endpoint Protection download it and no negative effects are noted the reputation score goes up until it is trusted. (for that HASH).
if the package is small .. i'd disable Norton and then submit the file here for analysis .. :
https://www.virustotal.com/then see if any other major vendors (Kaspersky, Sophos, Trend) flag the file. if they dont it is likely fine.
