This is a real and active problem for enterprises that is only recently being addressed comprehensively, using edge, network, device and application behaviour to detect, isolate and remediate the infection that may be sending information from your PC without any obvious symptoms.
So any improvement in consumer endpoint security, that starts to recognise and address the impact of advanced and persistent threats, should be applauded, regardless of the OS or the vendor.
