Windows Defender?

It’s important to understand exactly which “Defender” we’re talking about, since Microsoft continues to confuse us with their choice of product names.

  • Windows Defender was the name of a tool that only scanned for spyware

    and not other forms of malware, that ran in Windows XP, Vista and Windows 7. Microsoft Security Essentials (MSE), a tool that scanned for all types of malware, could be downloaded, and replaced Windows Defender when installed.

  • MSE was renamed Windows Defender in Windows 8, 8.1 and 10.

Windows Defender Offline is, effectively, the same Windows Defender anti-malware tool that comes with Windows 10.
