Source for Microsoft Windows Defender?

Hi folks. Can someone recommend a known, trustworthy site from which to download Microsoft Windows Defender? It’s been recommended, and I think it defeats the purpose to choose a site I know nothing about and invite it to download software to my computer. Thanks.

Thank you! There do not, however, appear to be updates for XP, so I may need to broaden the question to ask what I can install for XP that’s still supported. I run McAfee as my virus protection (which I have under my employer’s license).

I’d recommend doing a search in GQ for “spyware”. There’s a couple threads that recommend and compare the various offerings, most of all of which are free.
