WS.Trojan.​H Exonerated Files Found

I found 2 WS.Trojan.H Exonerated files in my norton history

 

Everytime I did a full system scan there was always one "WS.Trojan.H Exonerated" file that popped up in nortons history but now I recently did a scan and saw another "WS.Trojan.H Exonerated" file i thought it was the one i had been seeing all the time but when i checked it was a diffrent one so now i always get 2 "WS.Trojan.H Exonerated" that pop up in nortons history when i do a full system scan should I be worried? or is this because of nortons updates? also i would like to know if the files are safe because the scan said no treats found
