Tech support scams: how they work and how to spot them

Updated October 2026 · 4 minute read

A pop-up or caller says your computer is infected or hacked and gives a number for 'Microsoft' or 'Apple'. They take remote control and charge you, or empty your bank account.

How the scam works

Like almost every scam, this one follows a three step script:

  1. The hook. Something believable lands in front of you: a message, a call, an ad or a new "friend".
  2. The pressure. Urgency, fear, excitement or secrecy, so you act before you think or talk to anyone.
  3. The payment. A method that can't be reversed: gift cards, crypto, a Bitcoin ATM, or an e-Transfer to a stranger.

Spot any one of those three steps and you can stop the whole thing.

Red flags to watch for

  • Pop-up with a phone number and alarm sound
  • Asks you to install AnyDesk or TeamViewer
  • Asks you to log into your bank while connected
  • Pressure to keep it secret or to act right now.
  • Any request for gift cards, crypto, a Bitcoin ATM or an e-Transfer to a person's name.

What to do if it happens to you

Close the browser (force quit if needed). Real tech companies never cold call. If they had access, disconnect from the internet and get it checked.

If you already paid or shared details

  1. Call your bank or card issuer right away and ask them to stop or reverse the payment.
  2. Change any password you entered, and turn on two step verification.
  3. Report it to the Canadian Anti-Fraud Centre (1-888-495-8501) in Canada, or reportfraud.ftc.gov in the US.
  4. File a police report and keep every message, receipt and screenshot.
  5. Watch out for "recovery" offers. Anyone promising to get your money back for a fee is running a second scam.
