FW disabled after install of MS Office 2007 Enterprise

I’ve recently installed MS Office Enterprise 2007 from DVD. Initially I had to disable my comodo fw to get the install to complete normally. Once installed I rebooted as instructed and received error messages from FW that it was disabled and I was not protected. I uninstalled comoda fw and reinstalled it and everything seemed to work fine. After rebooting, my FW was again disabled and I was informed that I was not protected. I am using v 2.4 of fw. At this point in time I am also concerned that BOClean and cav are not really protecting me as well. Has anyone else seen this problem? What should I do now other then switch to another product security product.
