Martin JørgensenMicrosoft Windows Defender – Free antispyware from Microsoft.
When it comes to protection against spyware and unwanted software, Microsoft Windows Defender is a solid and effective choice—especially if you want something free and from a trusted publisher.
Windows Defender lets you scan, detect, and remove spyware before it can harm your system. The program works both defensively and offensively: it protects you in real time, blocks annoying pop-ups, and prevents unauthorized changes to your internet settings—a common target for spyware attacks.
The software is easy to use and runs smoothly in the background without slowing down your computer. Its threat definitions update automatically, so you’re always protected against the latest forms of malware.
Which version should you use?
✅ Windows 10 and 11: Windows Defender is already installed and integrated as part of Windows Security—you just need to make sure it’s enabled.
✅ Windows Vista and Windows 7: Here, it’s recommended to use Microsoft Security Essentials instead, which is the successor to Defender on these systems.
