OOP: Does Molly know?

Does Molly know that she was harboring a murderer in her house for 
13 years or so?  I was just thrown my the comment she made when 
asking Ron what sort of reward he wanted for becoming a prefect.  
SHe said he always like Scabbers.  And while that may have been true 
at the time, the knowledge of what/who Scabbers was I think is 
pretty much ruined any memories of him for Ron.  So was Mrs. Weasley 
being sightly insensitive, forgetful or just doesn't know?

The fact that she knows Sirius is a good guy makes me think she was 
eventually told the story, but it just seemed odd for her to ask Ron 
about him.

Also, does anyone think that Scabbers/Wormtail/Peter's knowledge of 
the Weasley's might come into play?
