You’re safe man, dont worry. 😄 These scammers just make you afraid so you panic and call them. They don’t have access to your PC — a popup is just a webpage yelling at you.
You didn’t click, didn’t call, didn’t share anything — so nothing stolen, you’re fine.
Just run a good antivirus scan (Windows Security or Malwarebytes), restart your PC, and you’re good. If you still feel scared, talk to Microsoft support — if they say the same words, it’ll relieve you. We’re all human, we make mistakes, it’s okay to ask.
Relax, take a breath. You handled it right. 🙏
