The ESET firewall is included in ESET Smart Security Premium and ESET Internet Security. Running two firewalls on your operating system can lead to conflicts and configuration errors. As a result, your ESET product will automatically disable your Windows Firewall after completing installation. Do not re-enable your Windows Firewall after installing ESET.
ESET NOD32 Antivirus is fully compatible with Windows Firewall. Windows Firewall is included with Microsoft Windows (XP/Microsoft Windows Server 2003 and later) and does not require a special configuration after installing your ESET product. ESET recommends leaving your Windows Firewall enabled after installing ESET NOD32 Antivirus.
