This was a tech support scam, not legitimate Microsoft Defender or Microsoft Security.

Key points based on what happened:

1. Real Microsoft error or Defender messages do not:
   • Lock the computer via a browser page.
   • Display a phone number to call.
   • Claim to show a list of “hackers” in specific locations.
   • Accuse of downloading or purchasing illegal content as a scare tactic.
2. Microsoft and other legitimate tech companies do not:
   • Cold call or ask to be called from a pop-up to “fix” the device.
   • Ask to check bank accounts, online purchasing accounts, or emails over the phone.
   • Transfer to supposed “FTC officers” who then ask for financial information.
3. What was seen matches known tech support scam behavior:
   • A fake Defender or security warning in the browser that appears to lock the machine.
   • A phone number to call a fake “Microsoft Security tech.”
   • Remote “scan” results showing fake hacking activity and fabricated accusations.
   • Pressure to review financial accounts while on the call.

Immediate steps recommended in this situation:

1. If any software or remote-access tools were installed or the scammer controlled the PC:
   • Uninstall any applications they asked to install.
   • Consider resetting the device to factory state if unsure what was changed.
   • Run a full scan with Microsoft Defender Antivirus and apply all security updates.
2. Protect accounts and identity:
   • Change passwords for Microsoft, email, banking, and other important accounts.
   • Monitor sign-in activity and account statements for unusual activity.
   • Contact the bank or card issuer immediately if any payment or card details were given.
3. Report the scam:
   • Report the incident to Microsoft at www.microsoft.com/reportascam.
   • If identity or financial data may have been exposed, follow identity-theft steps such as contacting banks, placing fraud alerts, and reporting to appropriate authorities as described in the references.

Going forward, if a similar pop-up appears:

• Do not call the number shown.
• Close the browser (Alt+F4) or use Ctrl+Alt+Del → Task Manager to end the browser process.
• Remember that Microsoft will never call unsolicited or include a support phone number in Defender or Windows error messages.
