How It Works

1
A fake pop-up message or browser window appears, warning of a critical security threat or the need for an urgent software or browser update. These messages are designed to look like legitimate notifications from companies like Microsoft, Apple, or Google and often use logos and urgent language to create panic.
2
The pop-up instructs the user to click a link to download the update or call a provided toll-free number for technical assistance. The message may freeze the browser or display a loud alarm to pressure the user into immediate action, warning that shutting down the computer will cause data loss.
3
If the user clicks the link, they unknowingly download malware, such as a remote access trojan (RAT), ransomware, or spyware. If they call the number, they reach a scammer posing as a technician who will request remote access to their computer to "fix" the non-existent problem.
4
Once scammers gain access, they may install malicious software, steal personal and financial information, or lock the computer and demand payment. They often charge a fee for the fraudulent "repairs" or sell unnecessary long-term security subscriptions.

Frequently Asked Questions

No, legitimate tech companies like Microsoft and Apple will never proactively contact you by phone, email, or with a pop-up message to report a problem with your computer. All support requests must be initiated by you, the customer. Unsolicited contact claiming a security issue is a scam.
These scams can lead to serious consequences, including the installation of malware that steals your personal information like bank logins and passwords. Scammers can also install ransomware that locks your files until you pay a fee, or they may directly steal money from your bank accounts after gaining remote access. This can result in significant financial loss and identity theft.
Immediately disconnect your computer from the internet to prevent further data transmission to the scammers. Run a full scan using a reputable antivirus program to find and remove any malware. It is also critical to change all of your passwords, especially for sensitive accounts like banking and email, and monitor your financial accounts for any unauthorized activity.
Yes, this scam affects people of all ages. While older adults often suffer higher financial losses, research from Microsoft shows that Gen Z and Millennials are more frequently exposed to and victimized by tech support scams. This is often because younger generations engage in more online activities that can expose them to these threats.
