How the scam works

A caller says they are from Microsoft or Windows support and that your computer has been hacked or is full of viruses.
Or a loud pop-up warning appears on your screen, will not go away and tells you to call a number.
You are asked to install a remote access program so the “technician” can “fix” the problem.
With that access the criminals can watch your screen, open your online banking or install malware.
In the end they demand payment for the “repair” or a “protection plan”, often by card or gift card code.

How to spot it

You did not expect the call. A genuine company does not phone you out of the blue about your computer.
A pop-up demands that you call a number immediately and cannot be closed normally.
You are told to install a remote access program or read out a code.
There is time pressure: “your data is at risk, act now.”
They ask for payment by card, bank transfer or gift card code.

What to do now

Just hang up. You do not owe the caller an explanation.
Do not call any number shown in a pop-up and do not install anything because a caller tells you to.
Close the pop-up through the task manager or restart your browser. If needed, switch the computer off.
Never open your online banking while a stranger is on the phone or watching your screen.
Tell family and friends about the call so they are warned too.

Already clicked or paid?

Disconnect the computer from the internet right away and uninstall the remote access program.
From a different, clean device, change your important passwords, starting with email and online banking.
Call your bank using the number on your card and have the card and access blocked if needed.
Have the computer checked or reset by a trustworthy professional.
Report it to the police and to your consumer protection service.

Frequently asked questions

Does Microsoft really phone private customers?

An unsolicited call about a supposed virus is a typical sign of this scam. The criminals misuse the name of a well-known company.

My screen is locked and a pop-up shows a number. What now?

It is only a web page, not a real alarm from your computer. Close the browser, using the task manager if needed, and do not call the number.

I only spoke to the caller for a moment. Is that a problem?

The conversation alone is usually harmless. It becomes serious if you installed something, gave out details or paid. Then follow the steps under “Already happened”.
