I learned that my CA software was not operating

I learned that my CA software was not operating properly because I still have Norton anti-virus on my system. CA support told me to uninstall Norton and reinstall CA. I downloaded the Norton removal tool but was unable to start the uninstall because I apparently still have leftover files on my system from an aborted install of winfax pro. The Norton removal tool instructed me to uninstall winfax pro before proceeding, but all attempts to do so have failed. I downloaded symclean from norton, but it failed to remove it. I downloaded ccleaner, but it failed also. I even removed all winfax files and data from the registry and temp file, but the norton removal tool continue to tell me to remove winfax pro. I called norton tech support, but they no longer support winfax. So I'm stuck.
