When I turn on Avast real site protection, I cannot access login.live.com due to 2FA redirect. Or I can’t access the microsoft User Login page either.
I reinstalled windows because I couldn’t solve it in the first place. I solved it by chance on my second computer.
Microsoft does 2FA or DNS forwarding for security reasons.
Because the page is blocked by Real Site, we cannot open a microsoft account via windows or browser. I forwarded the issue to avast company.
For your information,
