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…
But that often leaves behind the registry entries which may or may not cause problems.
And whatever menus and shortcuts, which are usually cleaned up by the uninstaller
