Live OneCAre doesn't like Quickbooks Pro 2009

Every couple hours Live OneCare's icon changes from green GOOD to yellow
FAIR. It then reports the "PC problem needing fix" as a stalled printer
queue. Digging a little deeper reveals the printer queue that is jammed is
Quickbooks 2009 Pro's "Quickbook PDF Converter."

I can let OneCare "fix" the problem and the icon turns green, but three or
four hours later the printer queue error returns.

Is there a known problem between Quickbook and OneCare? Or does anyone have
an idea what I might do to further troubleshoot this problem?
