The Scam Shield
A fake warning is built to make you act before you think. This guide shows you how to close one, how to spot the next one, and what to do if you already clicked. No shame, no jargon, and no number to call.

The warning is the product
A full-screen message that says your computer is infected and gives you a number to call is almost never real. Real security software does not put a support line in a browser warning, and it does not ask you to call anyone. The warning exists to create a moment of panic. The panic is the scam.
The same script arrives in different clothes: a red alert with a siren sound, a page that pretends to scan your files, a countdown that says your data will be deleted. None of them has scanned anything. A web page cannot see the files on your computer, and no warning that appears inside a browser can delete them.
Close it without calling the number
Do not call the number on the screen, and do not write anything down from the page. If the browser is stuck in full screen, press Escape. Close the tab, then close the window. If the window will not close, quit the browser from the taskbar or the app switcher and open it again without restoring the same page.
If the page asks to send notifications, choose block. If it asks to install anything, close it before you answer. A warning that keeps coming back after a restart is a reason to stop using that browser profile until someone checks it.
A page that asks you to install a remote-support tool is the same scam in a second costume. No legitimate warning needs a stranger to control the computer. Close the page, and if a program was already installed, remove it or bring the machine in.
The gift card is the tell
No bank, utility, delivery company, or government office asks to be paid in gift cards. A gift card is cash in a form that cannot be traced. Once you read the code to someone, the money is gone, and the store that sold the card cannot put it back.
The request usually comes with a deadline: pay in the next hour, or the account closes, or someone is arrested, or a package is returned. The deadline is there to stop you from checking. Hang up and call the organization on a number you find yourself, not the one in the message.
A real technician does not call you about a virus on a machine they cannot see. If someone rings our number and offers to fix a computer they cannot see, that is not how this shop works, and it is not how any honest shop works.
A message that is almost right
A phishing text or email copies a real sender's name, logo, and wording. The return address is the part that gives it away: a bank name spelled with an extra letter, a domain that is not the one on the company's own site, a reply-to address that goes somewhere else.
Do not use the link. Open the company's site by typing its address yourself, or call the number printed on your card or bill. A real company will not ask for your password, a code sent to you, or remote access to your computer in a message that arrived out of the blue.
One more check costs a minute: read the message out loud to someone else. A request that sounds strange in your own voice usually is.
If you already clicked or paid
If you gave someone remote access, disconnect from the network. Change the password for the account you shared from a different device, and turn on two-factor authentication if it is not already on. Call your bank if card or account details were entered, and ask what to watch for.
There is no shame in this. These pages are built by people who do it for a living. What matters now is the machine. Bring it in if you are unsure what was installed, if the browser keeps reopening the same page, or if the machine is behaving differently.
When to bring it in
Bring the device in if you gave remote access to someone you do not know, if a warning returns after a restart, if a program appeared that you did not install, or if the machine is slower, hotter, or noisier than it was. Bring the message with you if you still have it; a photo of the screen is enough.
We check what is installed and what changed, remove what can be removed, and explain what we found. Virus and scam cleanup is a published $89 service. If the machine needs a deeper look first, we will say so before any work starts.
