[KB2390] Are ESET products compatible with Windows Defender?

Solution

Microsoft Windows Defender is a program that comes enabled by default with Windows Vista, Windows 7, Windows 8, and some version of Windows 10.

You are not required to remove ESET on Windows 10

Depending on your version of Windows 10, you may receive a notification from Windows suggesting that you disable ESET. You are not required to disable ESET to use Windows 10. See our Knowledgebase article for details about Windows Defender behavior.

We recommend that you disable Windows Defender to continue using ESET without receiving notifications.

  • Windows 10: By default, Windows Defender Antivirus is disabled (turned off) with a compatible version of ESET installed on the system. No further action is required by ESET users.
  • Windows 8: If you receive a "Detection of installed security software" notification while installing ESET on Windows 8, disable Windows Defender before you continue the installation process.
  • Windows Vista/7: All ESET products are completely compatible with Microsoft Windows Defender. Windows Defender does not contain any antivirus functionality, so you will not need to uninstall or disable Microsoft Windows Defender when installing your ESET product.
