Genuine software reportedly a setback (7)
I believe the answer is:
relapse
'setback' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for relapse that I've seen before include "Fall ill again after rallying" , "go back" , "Regress, fall back" , "Get into bad habits again" , "falling back" .)
