Login to Feedback site blocked because of URL:phishing attack

When I attempt to login to feedback.minecraft.net website, the usual Microsoft Live popup appears. Logging in returns an AVG Antivirus warning that feedbackloginppe.azurewebsites.net is blocked because it is infected with URL:phishing. The browser reports the connection is reset (ERR_CONNECTION_RESET).

I can login safely to the XBox website or the Microsoft Store, however.
