Received a Suspicious Chrome Update Notification? How to Spot a Virus
We all rely on browser extensions to simplify our daily tasks, but sometimes trusted tools can turn against us. Recently, users worldwide have been targeted by a sophisticated scam that uses fake "critical update" pop-ups to trick victims into downloading malicious files.
How the New Scam Works
The scam begins with an aggressive prompt urging users to update their browser to continue browsing. Clicking the button triggers the download of a malicious executable file with a vbs or exe extension. What makes this threat particularly dangerous is that leading antivirus programs often struggle to detect it. The browser itself is not infected; instead, a previously installed extension acts as a gateway, pulling malicious code from an external server and displaying fake alerts directly within your browsing window.
This issue is not limited to Google Chrome; users of browsers like Brave and Opera have reported identical alerts. Hackers often purchase legitimate extensions or hijack developer accounts to distribute "silent" updates that bypass extension store security protocols. Among the recently identified infected tools is the popular extension "Enable Right Click & Copy Smart Unlock + OCR", which boasts 70,000 downloads and a high user rating.
How to Protect Your Computer
If you encounter a persistent update request, do not click any links and do not run any downloaded files. Always check for official updates through the browser's built-in settings menu. If alerts continue to appear, follow these steps:
-
Open your browser's extension management page.
-
Disable extensions one by one, focusing on those recently installed or minor utility tools.
-
Check if the pop-up disappears after disabling a specific extension.
Ultimately, the best defense is vigilance. Remember that modern browsers update automatically or via internal settings and will never require you to download an external file to continue using them.
