Microsoft has rolled out a groundbreaking security feature for its Edge browser today, introducing an AI-powered scareware blocker designed to protect users from sophisticated online scams. This new Microsoft Edge defensive tool, which operates using local machine learning capabilities, represents a significant advancement in browser security.
How it works
The scareware blocker employs computer vision technology to analyze full-screen pages by comparing them against thousands of known scam samples. Importantly, this analysis happens entirely on the user’s local device, ensuring privacy by not transmitting or storing images in the cloud. When the system detects a potential scam, Edge automatically exits full-screen mode, stops any audio playback, and presents users with a warning and thumbnail of the suspicious page.

The new security measure works in conjunction with Microsoft Defender SmartScreen, creating a multi-layered defense against online threats. While SmartScreen handles known scams, the scareware blocker specifically targets new and emerging threats that haven’t yet been cataloged. This real-time protection is particularly crucial as scammers increasingly employ sophisticated tactics to evade traditional security measures.
Why it matters
Microsoft’s data shows a dramatic increase in online scams, with Edge blocking five times more scams in 2024 compared to three years prior. Scareware scams typically use aggressive tactics to convince users their systems are infected with malware, often pressuring them to call fake tech support numbers that can lead to financial loss and compromised personal information.
How to enable
Users can activate the scareware blocker feature by following these steps:
- Open Edge browser settings
- Navigate to “Privacy, search, and services”
- Find the “Security” section
- Toggle on “Scareware Blocker”
- Restart the browser.
User participation
Microsoft Edge has implemented a feedback system allowing users to report both malicious sites and false positives. This collaborative approach helps improve the tool’s accuracy and contributes to the broader fight against cybercrime. When users report suspicious sites, the information is incorporated into Microsoft’s Defender SmartScreen service, helping protect the entire Edge user community.
Technical details
The feature utilizes WebUI 2.0 architecture, which minimizes code size and JavaScript execution during UI initialization. This optimization ensures the security feature doesn’t impact browser performance while maintaining robust protection against emerging threats.
This release marks a significant step forward in Microsoft’s commitment to user security, combining advanced AI technology with practical user protection. As scams become increasingly sophisticated, tools like the scareware blocker represent an essential evolution in browser security features, helping users stay safe while navigating the modern web.
