[KB2421] ESET firewall compatibility with Microsoft's Windows Firewall


End of support for Windows 7 / XP / Vista

This content references an operating system (OS) that Microsoft no longer supports or will soon stop supporting. Although ESET is committed to providing support for our products on any system, we do not advocate using an OS that no longer receives security patches. For more information about the Microsoft policy and upgrading your OS, visit our Knowledgebase article.

ESET Smart Security Premium, ESET Smart Security and ESET Internet Security:

The ESET firewall is included in ESET Smart Security Premium, ESET Smart Security 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:

ESET NOD32 Antivirus is fully compatible with Windows Firewall. Windows Firewall is included with Microsoft Windows (XP / Server 2003 and later) and does not require special configuration after installing your ESET product. ESET recommends leaving your Windows Firewall enabled after installing ESET NOD32 Antivirus.
