    Definition Update for Windows Defender - KB2267602 (Definition 1.217.1180.0) - Error 0x80070643

    When updating my version of Windows (Windows 10 Pro x64, Version 1511, OS Build 10586.218) in Windows Update I get the following error: Definition Update for Windows Defender - KB2267602 (Definition 1.217.1180.0) - Error 0x80070643 and am asked to retry.

    I am using Norton Security Deluxe version 22.6.0.142 with the firewall enabled and windows firewall disabled.

    Any suggestions on how to download definition for Defender?

    Regards,
