Microsoft Edge’s New Tool Shields You from Scareware
When was the last time one of those alarming pop-ups told you your computer was “infected”?
You know the kind — flashing red banners, urgent warnings and a fake “Microsoft support” number designed to scare you into acting quickly.
This scareware tactic is crafted to pressure people into paying for bogus support or granting access to their device. And even the most vigilant among us can be caught out.
Fortunately, Microsoft is stepping up its efforts — and using artificial intelligence to do it.
A major security boost for Microsoft Edge
Microsoft has released a substantial security enhancement to the Edge browser: a new AI‑powered scam protection tool that blocks fake warnings before they appear.
This update forms part of Microsoft’s broader mission to make Edge one of the most secure browsers for Windows and Mac users.
Key improvement:
- Scareware Blocker now built in and enabled by default on most newer devices.
How the new Scareware Blocker works
The tool uses advanced AI to recognise full‑screen scam pages designed to mimic real system alerts.
These include fake messages such as:
- “Your device is infected”
- “Call support immediately”
- “Critical system failure: action required”
When Edge detects one of these fraudulent pages, it:
- Closes it instantly
- Prevents any dangerous clicks
- Protects users without requiring any action from them
SmartScreen learns from every reported scam
If someone does report a suspicious pop‑up, Microsoft’s Defender SmartScreen automatically updates its protection worldwide.
This means:
- One user report can block the scam for many others
- Threats can be stopped hours or days before hitting global threat lists
- Microsoft’s protections improve continuously
In Microsoft’s own testing, a single user report protected around 50 other users from the same attack.
New scareware detection sensor (coming soon)
The latest version of Edge also includes a brand‑new detection sensor. It helps Microsoft identify new scams in real time — without sending personal data or screenshots.
At the moment:
- The sensor is disabled by default
- Microsoft plans to enable it automatically for anyone using SmartScreen
Why this matters for South African businesses
Scams are becoming more frequent and more sophisticated. A single wrong click can lead to:
- Compromised passwords
- Unauthorised financial access
- Ransomware attacks
- Business downtime and reputational damage
And while individuals are often targeted, medium‑sized South African businesses are increasingly in the crosshairs — criminals rely on a single employee making a mistake.
AI protection closes dangerous security gaps
Tools like Microsoft Edge’s new AI scam protection help:
- Reduce human error
- Block threats faster than traditional systems can
- Free up your team to focus on real work
- Strengthen your business’s overall security posture
If your business uses Microsoft Edge, make sure you’re running the latest version. This update could prevent a major incident — and avoid a few heart‑stopping moments along the way.
