Do I need a firewall & AV for Windows 10 if I'm installing it in a virtual machine?

[Ricochet J]

My daily operating system is KDE Ubuntu (KUbuntu). The last time I used Windows was 3.5 years ago (Windows 7).

I now need to use Windows from time to time.

If I install Windows 10 in a virtual machine (in KUbuntu) does that Windows 10 virtual machine need a firewall and anti virus suite?
