Security features for Xubuntu on Virtual Machine?



As a Windows user I’m pretty used to having all the essential security features running (firewall, antivirus, etc…), but I was also wondering whether these need to be installed on the Xubuntu running on the VM.

From the bit of googling I did I learned that Linux is usually not a target for malware and apparently most Linux users don’t use anti-malware. But is there a different recommendation if I’m running Linux through a VM on Windows?
