KB Solution ID: KB2390|Last Revised: September 9, 2014

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

  • 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 security product.
  • 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. To do so, follow the steps below:

To Disable Windows Defender in Windows 8

  1. Press the Windows  key + Q to search.
  2. Type Windows Defender in the Search field and click Windows Defender.
