NOOB: How to Uninstall SpamSieve with Hazel?

Hello,
I am trying to get all of the SpamSieve program deleted/uninstalled from my Air.
I thought I had uninstalled it correctly from the beginning but I keep getting an error box each time I restart my computer advising cannot locate SpamSieve. I just downloaded Hazel in hopes of completely uninstalling SpamSieve. Can someone please tell me how to use Hazel to uninstall/delete the SpamSieve program completely?
Thanks.
