I have installed the Firewall only. I then specifically disabled Defense+ permanently and also Execution Control and Sandbox in the settings, see:
However, I still get a warning of some unrecognized malware from the Cloud Scanner (when using Super).
I think if I uncheck those options below it stops, but I believe it should be disabled simply with the main “switch” at the top, so it looks like a bug to me.
System is Windows 7 64bit, everything updated.
