Behavior is different each time, some times it just loas a white screen and can't do anything, can't scan, can't see firewall settings, can't see anything on the menu; sometimes it loads de UI but whenever you try to access anything it just puts the screen in red and a message that says "Module error. Failed to load module SecurityFirewall".
Already did the uninstall method with the cleaning tool and secure boot several times, cleaned registry and folders, anything changes. Windows 10 Pro 1803 Avast Internet Security.
Having paid for a security software that is just sitting there is not nice at all. Looking forward to uninstall it and go with another solution.
