Is 'Hardened mode' enabled by default?

Is ‘Enable Hardened mode’ a setting that’s turned on by default?

No it isn’t.

Ah ok, thanks for letting me know!

I have another question, and it probably doesn’t deserve its own thread since I already opened this one.

Is ‘Enable Avast email signature’ a setting that’s turned on by default?

Thanks again

Yes, that option is enabled by default. You can turn it off if you like.
