I have already uninstalled Microsoft Defender following Microsoft instructions:
Open Finder > Applications. Right click on Microsoft Defender for Endpoint > Move to Trash.
Defender is not in my Applications folder anymore.
However, System Settings > Network > Filters > Filters & Proxies still show Microsoft Defender, and it is enabled but with a yellow dot.
This filter does not have enabled the option to disable.
Any suggestion how to get rid of this filter?
Update: after restarting the machine, the icon is gone, but filter/proxy still shows up:
