Hello everyone! I am new to VM setup and there are some questions that I would like to ask you guys.
1) Do I need the Virtualbox Host-Only Ethernet Adapter running when VM is off? I don't see any network traffic at all in the adapter. I set NAT in the network configuration, and install all Oracle drivers during setup. I also don't see any Oracle Virtualbox services running in Task Manager while VM is off.

2) Can I make the adapter enable only when VM is on?
3) What is the best network settings mode to test malware or isolate VM network from host network to make sure they don't infect the host network?
