Virus popups
The virus popup is usually just a webpage
Updated 6 September 2026
You were looking something up. Then the screen went red, a siren started, and a phone number told you to call Windows Support right now. That is a webpage putting on a costume. It is not your antivirus, and it is not a technician who found you.
What you are looking at
A full-screen warning, often with a fake Windows or Apple look, a countdown, and a number to call. Your speakers may loop an alarm. The FTC’s own tech-support scam page says the same thing we will: hang up, do not give anyone control of the computer, do not pay. They do not reach you through a random site.
Close it without calling
On a phone, swipe the browser away. On a computer, force-quit the browser if the page will not let you leave. Restart if you have to. Then open the browser yourself and go to a site you type. If you already let someone remote in, treat it like a break-in: change passwords from a different device, and read what to do if you typed a card.
What this page will not do
We will not rank antivirus products or ask you to upload a file. We will not walk a business through ransomware. This page exists so you do not install the thing the popup is selling.
Quick answers
- Is my PC already infected?
- Usually no. A website can shout at you. It cannot install a virus just by showing a banner. The danger starts if you called them or ran a file they sent.
- Should I pay for their remote tool?
- No. That is how they get onto the computer.
- Where do I report this?
- FTC ReportFraud. If money left the account, your bank and IC3 as well.
This is general safety information, not legal advice. Scams change. If you need an official desk: FTC ReportFraud or IC3.
