That Pop-Up Is Not From Microsoft or Apple
Tech support scams use fake urgent warnings to trick you into calling a number — here’s exactly what’s happening and what to do
You’re reading an article or browsing a website when your screen suddenly fills with a warning. It looks serious — maybe a red background, maybe the Microsoft or Apple logo, definitely large urgent text. “YOUR COMPUTER HAS BEEN INFECTED.” “YOUR DEVICE HAS BEEN BLOCKED.” A phone number to call — right now — before the damage gets worse.
Sometimes there’s an alarm sound. Sometimes a voice. The browser might seem frozen. The whole thing can feel terrifying.
Here’s what you need to know: that warning is fake. Microsoft and Apple do not contact you through pop-ups. They never have. They never will.
What the Pop-Up Looks Like
These scam pop-ups are designed to look exactly like a real warning from your device’s security system. They typically include:
- A logo from Microsoft, Apple, or a familiar security program like Windows Defender
- Alarming text — “VIRUS DETECTED,” “CRITICAL ERROR,” “YOUR PERSONAL DATA IS AT RISK”
- A phone number in large bold text — the number you’re supposed to call immediately
- An audio alarm or a recorded voice warning playing through your speakers
- A browser window that seems impossible to close
They appear on computers, laptops, tablets, and phones. They can look convincing enough that even people who have heard about this scam have been caught off guard by a particularly well-made one.
The logos, the colour schemes, the fonts — scammers copy them carefully from real Microsoft and Apple pages. The goal is to make you feel, in the first panicked moment, that this is coming from a legitimate source.
It is not. No matter how real it looks.
What Happens When You Call the Number
If you call the number on the screen, someone answers — usually quickly. They’re friendly, calm, and professional. They tell you they’re a technician and that they can fix the problem for you. All they need is to take a look at your device.
What they’re actually doing is running a script.
⚠ Watch for this pattern
The hook: They confirm there’s a serious problem with your device — they “know” because you called the number on the alert.
The access request: They ask you to download a program — often something called TeamViewer, AnyDesk, or “Quick Assist” — so they can “look at the problem directly.” This gives them remote access to your device: they can see everything on your screen and control your mouse and keyboard from wherever they are.
The fake diagnosis: While connected, they run a scan and “find” dozens of viruses and errors. They show you technical-looking screens filled with warnings. These results are real tools — but the problems they appear to show are either normal or completely fabricated.
The payment demand: They tell you the repairs will cost anywhere from $150 to $600 or more. They may ask for payment by credit card, gift cards, or wire transfer.
The real damage: While they have remote access, they may steal passwords, access your banking, copy your personal files, or install malware that gives them ongoing access to your device even after the call ends.
According to the Canadian Anti-Fraud Centre’s 2024 Annual Statistical Report, service fraud — the CAFC category that includes tech support scams — was one of the three most commonly reported fraud types in Canada. In 2024, seniors absorbed 40 per cent of all reported fraud losses despite representing 23 per cent of the population. The CAFC estimates only 5 to 10 per cent of fraud is ever reported, which means the true number of victims is far higher than official figures show.
Why It Works — And Why That Is Not Your Fault
The pop-up is designed to do one thing: trigger panic before you have a chance to think.
When something appears to go seriously wrong with a device you depend on — for email, for photos, for keeping in touch with family — the fear of losing it is real. The alarm sounds, the frozen screen, the urgent language — these are all engineered to overwhelm your judgment and replace it with urgency. That’s not a failure of intelligence. It’s a deliberate attack on a completely normal human response to a perceived emergency.
The Microsoft and Apple branding makes it worse. You trust those names. You’ve seen them on your device for years. That’s exactly why scammers use them.
If this has happened to you — whether you called the number or not — that reaction makes complete sense. These pop-ups are built to work on everyone.
What To Do When You See a Pop-Up Like This
Don’t call the number
The phone number on the screen belongs to the scammer — not to Microsoft or Apple. Neither company will ever contact you through a pop-up, and neither will ever ask you to call a support number that appeared on your screen uninvited.
Close the browser — or close the tab
The pop-up almost always lives inside your browser. Try closing the browser window entirely. On a Windows computer, you can press Alt + F4 to close the active window. On a Mac, press Command + Q to quit the browser. If a single tab seems to be causing the problem, try closing just that tab first.
If the screen seems frozen, turn the device off
If you can’t close the browser, try forcing it to quit before resorting to a full shutdown. On a Windows computer, press Ctrl + Shift + Esc to open Task Manager, find your browser in the list, and click End Task. On a Mac, press Command + Option + Escape to open Force Quit, select your browser, and click Force Quit. On a phone or tablet, press and hold the home button or swipe the browser app away to close it. If none of those work, hold down the power button until the device shuts off completely. Wait a few seconds, then turn it back on. When you reopen your browser, do not restore the previous tabs — close the browser again and reopen it fresh. The pop-up cannot survive a restart.
Do not download anything and do not give anyone access to your device
If you’ve called the number and they’re asking you to download a program so they can “help” — stop. Hang up. Do not install anything. Remote access tools give scammers complete control of your device. Once they’re in, they can read your passwords, see your bank accounts, and install malware — even after you hang up.
If You Already Called the Number
Please don’t be embarrassed. These scams succeed on careful, capable people every day. The technology and the pressure tactics are genuinely sophisticated.
Here’s what to do, in order:
- If you gave them remote access to your device, disconnect from the internet immediately — turn off your Wi-Fi or unplug the internet cable — to cut off their access. Then do not turn the device back on until you’ve had someone check it.
- If you paid by credit card, call your credit card company immediately and explain you were scammed. They may be able to reverse the charge.
- If you paid with gift cards, keep the cards and the receipts and contact the retailer — recovery is rare but worth attempting. The card numbers are what the scammer wants; if you haven’t given them yet, don’t.
- If you shared any passwords, change them from a different, unaffected device as soon as possible. Start with your email and your banking.
- Have a trusted person check your device before you use it again — particularly for remote access tools or malware that may have been installed.
- Report it to the Canadian Anti-Fraud Centre: call 1-888-495-8501 or report online at antifraudcentre-centreantifraude.ca. Your report helps protect other Canadians.
- Contact local police if significant money was lost.
How to Help Protect an Older Parent or Relative
If you’re an adult child reading this on behalf of a parent, here are a few practical things worth doing before a pop-up ever appears:
✓ Do these now — before a pop-up ever appears
Have this conversation directly. Let them know that no matter what appears on their screen, Microsoft and Apple do not contact people this way — ever.
Agree on a simple rule: if anything scary appears on the screen, turn the device off and call a real person they trust before doing anything else.
Make sure they know how to turn the device off. A full shutdown is the single most effective response to a frozen or alarming screen.
Know the real support numbers. Microsoft‘s genuine support is at microsoft.com/en-ca/contact. Apple‘s genuine support is at apple.com/ca/support. Neither will ever call you or send you a pop-up first.
