Norton Diagnostic Report Auto Start program list has fst_us_189

The Auto Start program list has "fst_us_189" with no other information.No Location, No software vendor and no description. A search of the web list variations of the name as Adware. Does anyone have info on what it is and how to get rid of it. I have not received any messages about it being detected, just happened to notice it in the Norton Diagnostic Report.
