Looking to setup VM in Virtualbox to test malware

Want to test some security software including VoodooShield and want to setup VM in Virtualbox to do it

Just want to make sure that the guest cannot talk to the host in anyway or and communications outside of the vm

I have take screenshots of the settings I plan to implement to stop the guest communicating outside the VM and making sure that it is safe to test

1. 
2. 
3. 
4. – this I am not sure about
5. – this I am not sure about
6. – this i am not sure about

Anyway,

• Turn off windows defender on gues
• Remove the host for Wifi/ network
• Have Voodooshield running in the host

that is how I am proposing to do this…am I missing something?
