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…
I wouldn’t trust that uninstaller to actually uninstall any of the malware that “firewall” installed. Purge the program directories manually.
Honestly just reinstall Windows, it’ll be faster than trying to get rid of the McAfee infestation.
