the compliance issue

### What is this about?

There is no critical security warning displayed within the MetaMask interface.
As a MetaMask user, I am deeply concerned about this lack of clear security messaging. This warning is an important compliance measure to ensure users understand the risks and take responsibility for protecting their own systems.
By not prominently displaying this warning, MetaMask may be failing to adequately inform and educate its users about the potential consequences of a compromised machine. This could put user funds and accounts at serious risk.
