Scary Pop-Ups: What They Are, Why They Happen, and What To Do Immediately
Scary Pop-Ups: What They Are, Why They Happen, and What To Do Immediately
When I was studying for my masters degree and had to do research papers searching the internet for papers and articles to use in my project. Then, to my surprise, I received one of the scariest pop-ups I had ever seen. Your machine is infected and take action NOW to clean your computer. This was before I was in cybersecurity and knew what to do and I freaked out.
I work in cybersecurity, and these pop-ups are one of the most common scams I see—but also one of the easiest to avoid once you know the signs.
What Are “Scary Pop-Ups”?
Scary pop-ups are fake security alerts that appear in your web browser. They pretend to come from Microsoft, Apple, antivirus companies, or even law enforcement — but they are scams designed to scare you into clicking, calling, paying, or installing something dangerous.
These pop-ups often use:
Loud alarms
Flashing red warnings
Fake system alerts
Threats such as “do not shut down your device”
These are designed to be scary. Scammers want to frighten you into calling or taking immediate action.
These scams come in a few common forms, but they all rely on the same fear-based tactics.
Common Types of Scary Pop-Ups
Scareware
Pop-ups that tell you your device is infected and push you to “buy protection now.”
Malware Installers
These trick you into downloading “security tools” that are actually harmful software.
Fake Tech Support Scams
These claim you must call a support number. The person who answers is always a scammer.
I’ve had people tell me that a family member—a mother, aunt, or grandfather—has fallen victim and allowed fake tech support on their computers to later lose thousands of dollars from their checking accounts. This is more common than people realize, especially when pop-ups look so real and similar to the legitimate anti-virus tools or applications we use daily.
What To Do Immediately: Stay Calm & Follow These Steps
QuickTip: Calm actions protect you more than panic. Follow this process!
STOP – Don’t click or call
CLOSE – How to safely close the browser
CHECK – What to scan (and what NOT to install)
PREVENT – Reduce future risk.
Steps to follow
Do NOT click anything inside the pop-up — not even Close or Cancel.
Close the tab or browser window:
• Windows: CTRL + W
• Mac: Command + WIf the browser will not close, force-quit it:
• Windows: CTRL + ALT + DELETE → Task Manager
• Mac: Command + Option + EscapeRun a trusted antivirus or built-in system scan.
If you accidentally clicked or installed something:
• Disconnect from the internet
• Run a full security scan immediately
Scammers rely on fear to push people into quick decisions. Pausing for even a few minutes can stop the scam. The main thing is to pause and take a few minutes to breathe. This will help in the long run.
How To Avoid Scary Pop-Ups in the Future
Keep your browser and operating system updated.
Turn on pop‑up blocking in your browser settings.
Avoid clicking suspicious email or text links.
Only download software from official company websites or app stores.
Teach kids and seniors what these scams look like.
Download an additional tool that adds more protection to the browser. FYI Antivirus solutions protect against traditional viruses. Malwarebytes catches newer, trickier, sneaky threats. Think of it like this: the Antivirus (Front door lock) and Malwarebytes (security alarm and pest control). Both of these tools do different things and can add another layer of protection which can be used side by side and can co-exist.
The Golden Rule
Never trust a pop‑up that demands urgent action. Close the browser. Run a scan. Move forward with confidence.
Wrap-Up & Reassurance
These scams are designed to scare and confuse good, smart people. Awareness and calm action are the best protection. If this happens, remember: pause, close, scan — and you are usually safe.
In most cases, these pop-ups look frightening, but your device is not infected.
