How To Uninstall Mcafee Completely

I recently purchased Bitdefender Total Security 2014. I am now trying to install the product. When I attempt to install I get the following error message: 'Bitdefender 2014 cannot automatically uninstall McAfee. We recommend that you manually uninstall this program and run Bitdefender 2014 installation again.' I cannot find this McAfee under programs and features to uninstall. I have tried MCPR tool to remove McAfee, but it did not work. Please help me
