The technology
that changes daily life.

A normal webpage beneath a sudden, unexpected warning.

⊞ SECURITY NOTICE ACTION REQUIRED
!

CRITICAL WARNING · EXAMPLE ONLY

Suspicious activity
detected on this device.

For your safety, do not close this window. A support agent must verify your device immediately to prevent data loss.

FAKE HELP LINE: 1-800-XXX-XXXX
01 / FIRST RESPONSE

Pause. Close the tab.

Unexpected warnings that demand a phone call are a major red flag. Don't call the displayed number or grant remote access.

Practice: Click “Close this tab” in the example. You can also close the real browser tab normally.

YOU CAN ALWAYS STOP AND VERIFY INDEPENDENTLY.
02 / SPOT THE TRICKS

Notice the pressure.

“Critical,” “immediate,” “do not close,” a mystery infection, and a fake helpline are designed to make you act before you think.

Real support companies do not diagnose infections from an unrelated webpage popup.

NEVER PAY WITH GIFT CARDS OR CRYPTOCURRENCY.
03 / STAY IN CONTROL

You've got this.

If you gave access or payment details, stop the session, contact your bank through official channels, and change important passwords from a separate trusted device.

For suspected malware or persistent alerts, ask a verified technician for guidance.

ASK SJK FOR HELP THROUGH ARES — NOT THROUGH THE POPUP.
