I used a flat screwdriver and wedged it between the screw and trim and put some force on it. It still would spin and not come out at all. I am going to replace the guard due to all the epoxy on it I must have driven through. That is, if I can get it out. Incidently, when I removed the closest bolt on the moulding from fender to fender and got my hand behind there, I found a good bit of road grime. I am thinking that on the next nice weekend I am going to remove that moulding as well and clean behind it. Of course I have to figure out how to remove it.
