I initially only installed “Comodo Firewall” but for some reason they also installed a “Comodo Dragon Browser”, which I did not consent to. I always choose the “advanced” installation to uncheck bloatware, but in this case there was none and when you try to uninstall the browser, they force you to participate in their survey otherwise you won’t be able to uninstall the software…
You should you Revo Uninstaller to properly uninstall software and clean the regedit at the same time. It cleans everything
Also, a good and powerful firewall is “Safing Portmaster”
