Not that I want to keep you from doing something cool with AutoIt, but have you seen NiNite.com? You'll find that Malwarebytes is one of the options. It is an awesome utility, we use the paid version all day long at my company, saves us hours of labor each week! The free version is just as good though, so long as you have a net-connection on the target computer. It won't configure it for you however, so you may still want to use AutoIt for that.
