johnny223. Just for grins I uninstalled my previous firewall, (Comodo) and downloaded Webroot Firewall version 5.5.10.8. During the installation of it I got a notice that webroot said I had a version of Online Armor and Comodo Firewalls on my computer. These firewalls were NOT on my computer, maybe some residual files were. But Webroot allowed me to continue on with the installation, just said that it might not operate as efficiently if there were other 3rd party firewalls. I believe you can install webroot firewall and it should operate fine. Webroot is as far as I can tell operating fine on my pc.
