Start querying the application reputation service.
@remarks aCallback may not be null. onComplete is guaranteed to be called
on aCallback. This function may not be called more than once with
the same query object. If any of the attributes of aQuery have
not been set or have been set with empty data (with the exception
of sourceURI), then a valid request can still be constructed and
will solicit a valid response, but won’t produce any useful
information.
| aQuery | The nsIApplicationReputationQuery containing metadata of the downloaded file. |
| aCallback | The callback for receiving the results of the query. |
