Microsoft has rolled out a major security update to Windows users, introducing a new “Scareware Blocker” for Edge to combat rising scam threats.
The move comes as the FBI warns that tech support scams cost victims over $1 billion annually.
What’s Changing?
Microsoft reports that scareware scams—fake virus warnings urging users to call tech support—have become more aggressive.
These scams can hijack screens, play warning sounds, and mimic real security alerts. Even cybersecurity professionals have fallen for them.
The new Scareware Blocker in Edge uses machine learning to detect and shut down deceptive full-screen alerts before they can trick users.
Unlike traditional defenses, this AI model runs locally on the computer, ensuring privacy.
How It Works
- Stops full-screen scareware pop-ups
- Blocks aggressive audio warnings
- Warns users and shows a screenshot of the scam
- Allows users to report false positives for better accuracy
Edge already uses Microsoft Defender SmartScreen to block known scam sites, but this update adds a first line of defense against new, undetected scams.
How to Enable It
The feature is rolling out as a preview for Windows PC users. To activate it in Edge:
- Update Edge to the latest version
- Enable preview features under ‘Privacy Search and Services’ settings
What If You Don’t Use Edge?
Security experts recommend staying cautious of pop-ups, using ad blockers, keeping software updated, and never calling numbers from random alerts.
While Microsoft has faced backlash over buggy updates, this new feature is a significant step toward AI-driven, on-device security.
