Your answer

Next step

Leave the webpage. If you are concerned, open the security software already on your device or use support you already trust.

Takeaway

Check your computer without following the warning’s instructions.

Why this is safer

A webpage can imitate a security warning and supply its own support contact. Following its instructions is not a separate check. Use your existing security app or a support service you already know.

See all answers
  1. Leave the page and check through my usual security app.

    The warning cannot verify itself. Your existing security app is a separate route.

    A warning on a webpage is not proof that your computer has a virus. Leave the page. If you’re concerned, open the security software already on your computer or use support you already trust.

  2. Use the support contact shown in the warning.

    The warning may be directing you to a scammer.

    The person who answers could ask for payment or access to your computer. Don’t use the warning to choose who helps you.

  3. Try the warning’s Scan now button before deciding.

    The warning’s own button is not an independent check.

    Use your existing security software instead of following instructions inside the unexpected message.

  4. Trust the support number if a search result looks official.

    Finding the number online does not verify it.

    Scammers can appear in search results too. Use a support website or contact route you already know is genuine.

Optional practice — simulated screens

Try the next step

Choose a screen to open. Nothing outside this practice page will open.

The illustrated warning

The warning offers to check its own claim.

This is part of the same unexpected webpage. Leave it and choose your existing security app.

Security app already on your device

You open the app from your own device menu.

You chose a separate way to check. This practice screen does not scan your device or claim it is safe.

Support supplied by the warning

The page directs you to its own support team.

The warning is choosing who would help you. Use a support route you already know instead.

Practice complete

Challenge complete.

You practised choosing your own route to security help.

Next situation:

Park. Scan. Pay?

Exploring a situation is practice, not proof that you will spot every scam.
