She's Back (1989)

Paul is a meek electrician who, with his nagging, dominating wife Beatrice, moves to a new house in a neighborhood stricken by a series of robberies. That night, the gang responsible breaks into their house, beats up Paul, murders Bea, and makes off with the valuables. As Paul is coming to terms with his wife's death, she appears as a ghost only he can see and hear, nagging him into hitting the streets (later with his garbageman neighbor) and avenging her, with some interesting methods of doing so...
