I let a stranger remotely control my computer. What should I do?

Reviewed answer

Disconnect the computer and secure important accounts from a different trusted device.

Turn off Wi-Fi and unplug Ethernet to end the connection.
From another trusted device, contact your bank if financial accounts were exposed and change important passwords.
End unfamiliar account sessions and review recovery details, purchases, and transfers.
Use the computer maker's support to remove remote tools and assess whether a reinstall is needed. A clean scan alone is not proof of safety.
