Expedition Autorouter - don't want via in pad

I foolishly auto-routed without realizing that the autorouter would put a via in a surface mount pad.  Two questions: 

1.  How can I clean up my design to undo the via in pads that autoroute put down.  I don't want to lose everything that the autorouter did though.

2.  When using autorouter in the future, how do i specify to it not to put a via in a pad.
