Using a firewall with a VPN results in you being unable to share files and use some other VPN features. Antivirus and security software programs may offer their own firewall protection and may display a message asking if you want to switch. Check their features against Windows and then decide, but usually most firewall features are comparable. The important thing is to have one activated.
