Is UEFI more secure than BIOS on a Windows 8.1 machine?

Is UEFI vulnerable to malware in ways that Legacy BIOS is not?

Is it correct that UEFI can connect to the internet before the OS (or anti-virus program) has loaded? On some boards, UEFI settings can be changed in Windows. Do these things affect PC security?

I have read that BIOS on an MBR disc can be vulnerable to 'rootkits' There have been reports that suggest UEFI secure boot may not be infallible. Is UEFI better at defending against malware than BIOS?
