Sophos Mac Free Edition Problem

So, after much searching hopefully this will help me fix this problem. I've been trying to remove Sophos for months now after downloading the free edition onto my macbook, which is running 10.6.8

After unsuccessfully purging my device of this program I tried just chucking it in the trash and deleting it but the SophosUIServer continues to run. I can't shut down my computer, I can't do squat. I have coppied the portion from the Console's instal.log section.

Oct 13 13:14:39 CamsComputer Sophos Installer[1806]: "installer.localPayload.buildPlan" success: YES
Oct 13 13:19:41 CamsComputer Sophos Installer[1806]: Receipt proxy sent exception. connection timeout: did not receive reply
Oct 13 13:19:41 CamsComputer Sophos Installer[1806]: "installer.localPayload.remoteRemove" success: NO
Oct 13 13:19:41 CamsComputer Sophos Installer[1806]: "installer.localPayload.installComponents" success: NO
Oct 13 13:19:41 CamsComputer Sophos Installer[1806]: "installer.localPayload.launchServices" success: NO
Oct 13 13:19:41 CamsComputer Sophos Installer[1806]: "installer.writeReceipt" success: NO
Oct 13 13:19:41 CamsComputer Sophos Installer[1806]: "installer" success: NO

So, What does this mean? How do I fix it? And how on earth do I get this software off of my computer for good? I've tried running the uninstaller and it makes it about 25% and just stops progressing... HELP!!!!!!!! :)
