I have a subscriptions and was trying to install antivirus on my Mac (Sierra), but it's telling me that I previous version is on the computer and I can't install the new one because of the old version. Now I can't seem to close the old version so that I can uninstall it. I've gone to the activity monitor and tried to quit/force and it keeps popping back up. Help
