Handle a suspicious computer warning
Step 1 of 5: Pause the conversation
Do not call a number shown in a frightening pop-up, install a requested remote-control app or share a verification code. Unexpected calls claiming to repair your computer should be checked independently.
✓ Step complete. You can practise it again.
Step 2 of 5: Close the page safely
Try closing the browser tab or window. If the page prevents this, use the device’s app-switching controls or Task Manager to close the browser. Reopening the same tabs may bring the warning back.
✓ Step complete. You can practise it again.
Step 3 of 5: Check through a trusted route
Open your device’s built-in security app or support website yourself. Microsoft says its error messages do not contain support phone numbers. Use a contact you obtained independently rather than one supplied by the caller.
✓ Step complete. You can practise it again.
Step 4 of 5: Respond to what you shared
If someone controlled the computer, disconnect it from the network and seek trusted help. From a separate trusted device, change affected passwords. If you paid or exposed financial details, contact your bank promptly.
✓ Step complete. You can practise it again.
Step 5 of 5: Report and keep a record
Keep the date, messages and payment information without reopening dangerous links. Report the incident using the relevant service’s official scam channel. In the UK, suspicious emails can be forwarded to report@phishing.gov.uk.
✓ Step complete. You can practise it again.

A common question.
Does closing the pop-up remove all malware?
No. If you installed software, gave remote access or still see unusual behaviour, further checks with trusted support are needed.
