t happens fast. You're browsing the web normally and then suddenly a loud alarm starts blaring from your speakers. A bright red warning fills your screen. It says your computer is infected, your banking information is exposed, and you need to call a number immediately. Your mouse won't close the window. The whole screen feels frozen.

It's terrifying. It's designed to be.

But here's what's actually happening: your computer is fine. You landed on a malicious web page built specifically to scare you into calling a fake tech support number. The people on the other end will offer to "fix" your computer and charge you for it, often several hundred dollars, while doing nothing or making things worse.

The alarm is a sound file on a web page. The warning is just text on a screen. Nothing has actually happened to your computer.

How to Get Out of It

The trick this type of page uses is that it blocks you from closing the browser window normally. Clicking the X doesn't work. Clicking anywhere seems to make it worse. That's intentional.

Here's how to shut it down completely:

On a Windows PC: Hold down the Ctrl, Alt, and Delete keys at the same time. Select Task Manager from the menu that appears. Find your web browser in the list (it might say Chrome, Edge, or Firefox). Click on it, then click End Task. This forces the browser to close without giving the page any chance to react.

On a Mac: Hold down the Option, Command, and Escape keys at the same time. A small window will appear. Select your browser from the list and click Force Quit.

Either way, the page closes and the alarm stops. Your computer is exactly as it was before you hit that page.

One More Important Step

When you reopen your browser, it will often ask if you want to restore the tabs from your last session. Do not click restore. If you do, you'll load right back into the same page and the alarm will start again.

Just open a new tab and continue on with whatever you were doing.

Why This Works on People

These pages are polished and convincing. The alarm creates real panic. The warning looks like something from Microsoft or your antivirus software. And suddenly not being able to close the window makes people feel like something is genuinely wrong with their computer.

Scammers know that if they can keep you on that page for 60 seconds, fear takes over. And when people are scared, they call the number.

Real alerts from Microsoft or Windows never come through a web page. They appear as notifications from Windows itself, not as something that pops up while you're browsing. If a website is telling you your computer is infected, it's lying to you.

If Someone You Know Already Called the Number

This is important. If you or someone you know panicked and called the number, gave remote access to the computer, or paid for "service," please call us. There are specific steps to take right away to protect your accounts and make sure nothing harmful was left behind.

Don't be embarrassed about it. These scams catch sharp people every single day. The important thing is knowing what to do next.
