Is this a scam?

Had a worrying pop-up, phone call or message about your computer? Tick what happened and I'll tell you how likely it is to be a scam, and exactly what to do next.

Tick anything that happened:

The golden rule: genuine companies never cold-call about your computer, never put phone numbers in pop-ups, and never ask for your passwords. Read more in how to spot and avoid tech scams.

Every one of these scams follows the same four steps

Once you have seen the shape of it, it is very hard to unsee, and that is the best protection there is. Whether it arrives as a pop-up, a phone call, a text or an email, it runs the same way.

  1. Contact you did not ask for. You were not expecting it. Nothing you did caused it to appear.
  2. Something frightening. Your computer is infected, your account has been accessed, a payment is about to leave your bank.
  3. Pressure to act now. A countdown, a warning not to turn the computer off, someone staying on the line with you.
  4. A request only a scammer makes. Call this number, let me connect to your computer, confirm your card details, move your money somewhere safe.

Step four is where it becomes certain. A real company that already has your business does not need to ring you out of the blue and ask for remote access to your machine.

What real companies never do

If you already let them in

First: this happens to careful, capable people every day, and it is designed by professionals to work on exactly the people who think it would not work on them. There is nothing to feel daft about, and the sooner you act the better the outcome.

  1. Disconnect the computer from the internet, by unplugging it or switching off the Wi-Fi.
  2. Ring your bank straight away if any money or card details were involved. Use the number on your card, not one anybody gave you.
  3. Change your important passwords from a different device, starting with your email, because that is the key to everything else.
  4. Have the machine properly checked. Remote access software may still be installed and set to reconnect.
  5. Report it to Action Fraud, the UK's national fraud reporting centre, on 0300 123 2040 or at actionfraud.police.uk. Reports are what let the police link cases together.

Common questions

Will Microsoft or Apple ever ring me about my computer?

No. Neither company monitors individual computers, neither can see whether yours has a problem, and neither has any way of getting your phone number in that context. An unexpected call claiming to be from Microsoft, Apple, Windows or your internet provider about a virus is a scam without exception. Hang up. You do not owe them a conversation.

A pop-up says my computer is infected and gives a phone number. Is my computer infected?

Almost certainly not, and the pop-up itself is usually just a web page designed to look like a system warning. Real security software never puts a phone number on screen. Do not ring it, do not click anything inside it, and close the browser; if it will not close, restart the computer. Seeing one of these does not mean anything got onto your machine.

I let someone connect to my computer. What should I do right now?

Disconnect it from the internet, then ring your bank from another phone if money or card details were involved, using the number on your card. Change your email password from a different device first, since email is what everything else resets through. Then have the machine checked properly, because remote access software may still be installed and configured to reconnect. Acting within the hour makes a real difference.

They asked me to pay in gift cards or a bank transfer. Is that normal?

It is never normal, and it is one of the clearest signals there is. Gift cards, vouchers, cryptocurrency and direct bank transfers are demanded because they are hard to reverse and hard to trace. No genuine company, and no part of HMRC, the police or your bank, will ever ask to be paid that way. If someone has told you to buy gift cards, stop there.

How did they get my name and phone number?

Usually from data breaches or bought lists rather than anything you did wrong, and a name is often all they have. Knowing your name, address or even the last four digits of a card proves nothing about who is calling; that information circulates widely. Scammers open with it precisely because it makes people relax.

Should I report it if I did not lose any money?

Yes, and it genuinely helps. Action Fraud is the UK's national reporting centre, on 0300 123 2040 or actionfraud.police.uk, and near-misses are worth reporting because they let the police connect numbers, websites and bank accounts across many cases. It takes a few minutes. You can also forward suspicious texts to 7726, which is free.

Is a scam email dangerous if I only opened it?

Opening an email is generally safe. The risk is in what you do next: clicking a link, opening an attachment, or replying. If you clicked a link and then typed a password into the page it opened, change that password now. If you only looked at it and deleted it, you are fine.

Does this checker send my answers anywhere?

No. Nothing is recorded, stored or transmitted. It counts the boxes you tick in your browser and shows a result, and that is the whole of it. Nothing you tick reaches me or anyone else.
