Fake Virus Pop-Ups: How to Beat the “Your Computer Is Infected” Scam

You’re reading the news or checking email when — bam — the screen freezes. A bright red warning fills it: “WARNING! Your computer is infected. Call Microsoft Support immediately.” Maybe there’s loud beeping, or a robotic voice telling you not to turn off your computer.

It’s frightening by design. And here’s the first thing to know: it’s fake. Every bit of it. No real company will ever lock your screen and tell you to call a number. Let’s walk through how this one works — and how to shut it down in seconds.

How the scam works

There are two common versions:

The pop-up. A scary warning appears while you’re online, often with alarms and a phone number. If you call, a friendly “technician” answers, claiming to be from Microsoft, Apple, or “Windows Support.”

The phone call. Out of the blue, someone calls saying they’ve “detected a problem” with your computer.

Either way, the goal is the same. The “technician” asks to connect to your computer remotely “to fix it.” Once they’re in, they pretend to find serious problems, then:

• Charge you a fee to repair something that was never wrong.
• Ask for your bank or credit card details.
• In a nastier version, claim they “accidentally refunded you too much” and ask you to mail back the difference in cash or gift cards.

Some will even tell you to keep it secret — that’s a scammer protecting himself, not helping you.

The warning signs

• A pop-up or call says your computer is infected and gives you a number to call.
• You’re told to act right now and not turn off the computer.
• Someone asks to remotely access your computer.
• You’re asked to pay with gift cards, a wire transfer, or crypto.
• You’re told to keep it quiet.

Real warnings from your own antivirus software never include a phone number to call — and Microsoft and Apple never phone you out of the blue.

What to do

If a pop-up appears: don’t call the number, and don’t click anything inside it. It can’t actually harm your computer — it’s just a scary web page.

1. Close it. Close the browser tab or window. If the screen seems stuck, restart the computer (hold the power button if you must). The “virus” vanishes with it.
2. Never give anyone remote access unless you called a company you already trust.
3. Never pay with gift cards, wire, or crypto for tech support. No legitimate company asks for that.
4. When in doubt, walk away and ask someone you trust before doing anything.

If you already let someone in: don’t panic, and don’t feel embarrassed — this happens to careful people every day. Turn off the computer, call your bank if you shared any payment details, and change the passwords you can. A trusted family member or local computer shop can help you check the machine.

You’re not foolish — you’re targeted

These scams work because they’re loud, sudden, and built to scare you before you can think. Tech-support scams are among the most common schemes aimed at older adults — not because anyone “should have known better,” but because they’re professionally designed to create panic.

If one has cost you money, you’re not alone, and help is available. The AARP Fraud Watch Network Helpline (877-908-3360) is a free, friendly place to talk it through.

One last thing: share this with someone. A pop-up like this is far less scary when you’ve seen it described before it ever appears on your screen.
