Comodo firewall free y Avast Free antivirus

I recently installed the Comodo firewall and my Avast antivirus in the ineligente analysis detects that there is another antivirus installed. I checked several times and until I uninstalled and reinstalled, I deleted the other protection settings (internet security and proactive security) on the firewall, I deactivated viruscope, and it still detects it. In the security center of windows 8.1 it indicates that there are two spyware installed and points me to a Comodo Advaced protection How can I uninstall it or at least disable it? Because I do not want to be desetabilize my system and also the pc has made me slow … Thanks :-\

Comodo hasn’t been just a firewall for quiet a while.
Remove it completely.
For instructions see the Comodo website.
