You can't uninstall this software without being forced to participate in their survey
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..
Unless something has changed since I last needed it, Revo Uninstaller can scrub programs from your system.
First it runs the regular uninstaller. Then it scans program folders, user profiles, registry, etc. for any “missed” files. You can pick and choose what you want gone and it can back up any post uninstaller changes in-case you Bork something.
