Clean or Not Clean

Avast is current and updated. Ran full scan nothing found. Ran bootscan - result C: ProgramData{559F25A3-87D2-4D88-ADC5-DFC277CDD45}\SETUP.RES|>HSTART.EXE win32:HiddenStart [PUP]

Avast could not delete, repair, chest. re-ran full scan nothing found, repeat Boot scan completed with same results.

Is this a problem or false positive?
