Hello akiva31! 

Thanks for reaching out. I am sorry you are having issues and the support wasn't able to help you out.

This forum is for the "Enterprise Defender", and I need to admit, that I don't know much about the consumer version - but let's see if we can help you 🙂

When you say you can't access "Microsoft Defender", are you referring to the App or are you trying to access a specific site? 

 

Best,

Heike

HeikeRitter Yes, I am referring to the application for Windows. I had the feeling that the tech support representative I spoke with seemed to believe that I have the business version of Microsoft Defender, though I definitely have the consumer version, the version that comes with the Microsoft 365 Personal subscription. If you could help, then that would be fantastic.

      Gosh, I did not receive a notification for your message (or I missed it). I am very sorry.
      Did you see SJ27s reply and did you try the suggested steps?

        Not a problem. I did see SJ27s suggestions. I have already tried restarting, repairing, resetting, and completely uninstalling and reinstalling Microsoft Defender. Non of those worked. I also do not have any third party VPN apps.

        The only thing I am unsure how to do is determine if I have any proxy settings set for my internet that may block Microsoft Defender from accessing its URLs. However, I would imagine if this was the case I would have issues with other applications, though I could be wrong, I am willing to test this if you or SJ27 could provide me guidance as to what settings to check.
