Here's a talk about spiritual warfare with a prayer of exorcism at the end of the audio. Here's the description of the audio from the website:

A very powerful talk all Catholics should hear! The speaker is exorcist priest Fr. Clement Machado and the topic is on Spritual Warfare. In this eye-opening speech Fr. Machado talks at length about how the battle between Heaven and Hell is raging on around us, and how Satan is winning in our country right now. Between the genocide of the unborn, and the election of Barack Obama, we have grown weak and need to rise up as prayer warriors, trusting in the powerful name of Jesus, our Blessed Mother, and St Michael. This talk was given on November 22, 2008 in Chicago Heights. Fr Machado is a true warrior for Heaven who isn't afraid to speak the truth. The talk concludes with a very powerful prayer of exorcism and healing.
