It usually happens out of nowhere. You are reading the news or looking up a recipe, and suddenly the screen fills with a warning. It might flash, beep, or play a recorded voice saying your computer is infected and your information is at risk. It tells you to call a support number immediately and not to turn off your computer.

This is almost always a scam. Real security warnings do not work this way. Here is how to recognize these pop-ups, how to get rid of them, and what to do if you already called.

How to spot a tech-support scam

Scam pop-ups are designed to frighten you into acting fast. Common signs include:

  • A phone number to call. Legitimate companies do not put support numbers in pop-up virus warnings.
  • Urgent, alarming language. Phrases like "Do not close this window" or "Your data will be deleted."
  • Loud sounds or a voice. Beeping, sirens or a recorded message are pressure tactics.
  • Your browser seems locked. The page may go full screen or keep reopening when you try to close it.
  • It borrows a familiar look. Scammers often copy the colors and style of well-known tech companies so the warning seems official.

Scammers also call people directly, claiming to be from a tech company, your internet provider or even your bank, saying they have detected a problem with your computer. Unsolicited calls like this are a red flag.

How to close a scam pop-up safely

The pop-up is usually just a web page. It is not a real infection, and it cannot do anything unless you call or give someone access.

  1. Do not call the number and do not click anything inside the pop-up.
  2. Try closing the browser tab or window normally.
  3. If it will not close, force-quit the browser. On Windows, press Ctrl + Shift + Esc, select the browser in Task Manager, and click End task. On a Mac, press Command + Option + Esc, select the browser and click Force Quit.
  4. When you reopen the browser, do not restore the previous session, or the scam page may come right back.
  5. Restart the computer if the screen still seems stuck.

Afterward, run a scan with your security software for good measure. If the pop-ups keep returning, that can mean unwanted software or a malicious browser extension is involved.

What if you already called?

Many smart, careful people have been caught by these scams. They are designed by professionals to be convincing. If you called, here is what to do, step by step.

If you let them connect to your computer

  1. Disconnect from the internet right away. Turn off Wi-Fi or unplug the network cable. This cuts off their access.
  2. Do not let them back in. Hang up if they call again.
  3. Uninstall any remote-access program they had you install. If you are unsure which one it was, it is best to have a professional look.
  4. Assume the computer may be compromised. Scammers sometimes install additional software or create hidden accounts. A professional cleanup is the safest route.

If you gave them payment information

  1. Call your bank or card company immediately using the number on the back of your card, not one the scammer gave you.
  2. Explain that you were the victim of a tech-support scam and ask about disputing the charge and replacing the card.
  3. If you paid with gift cards, contact the gift card company as soon as possible with the card numbers and receipt.
  4. Watch your statements closely for the next few months.

If you shared passwords or personal details

  1. Change your passwords from a different, trusted device, starting with email and banking.
  2. Turn on two-factor authentication wherever it is offered.
  3. Consider placing a fraud alert or credit freeze with the credit bureaus if you shared sensitive details like your Social Security number.
  4. Report the scam to the Federal Trade Commission and to local law enforcement.

Protecting yourself and your family

  • Remember the rule: real companies will not contact you out of the blue about a virus, and they will not ask for payment in gift cards.
  • Keep your browser and operating system updated.
  • Talk to older relatives about these scams. A quick conversation can save a lot of grief.
  • Write down a trusted number for computer help and keep it by the computer.
  • Back up your files regularly so a scare never turns into a loss.

We hear from neighbors in Canton, Woodstock and all over Cherokee County who were frightened by these pop-ups. If you are ever unsure, hang up, close the browser, and call someone you know and trust.
