Malware Notification

That notification is a scam site notification, not a real Microsoft or Windows malware alert. These pages commonly use fake virus warnings to scare users into clicking, calling, or downloading something unwanted.

To remove it from Microsoft Edge:

1. If Edge is stuck or the pop-up will not close:
   • Right-click Start > Task Manager.
   • Select Processes.
   • Under Apps, right-click Microsoft Edge > End task.
   • Reopen Edge.
2. Block or remove the site’s notification permission:
   • In Edge, open Settings and more > Settings > Privacy, search, and services > Site permissions > All sites.
   • Select the suspicious website.
   • Find Notifications and set it to Block.
   Or, while on a site already allowed to send notifications:
   • Select View site information to the left of the address bar.
   • Under Permissions for this site > Notifications, choose Block.
3. Make sure pop-up blocking is enabled:
   • In Edge, open Settings.
   • Go to Cookies and site permissions.
   • Open Pop-ups and redirects.
   • Make sure Block (recommended) is turned on.
4. If pop-ups continue, block third-party cookies and clear browser cache:
   • In Edge, go to Cookies and site permissions > Manage and delete cookies and site data.
   • Turn on Block third-party cookies.
   • Clear browsing data and cache.
5. Check Windows Security for anything that was blocked or needs action:
   • Open Windows Security and review Protection history.
   • If it shows Threat blocked, Defender already removed it.
   • If it shows Remediation incomplete, open the alert and complete the additional steps shown.
6. Scan the device for malware:
   • Run a malware scan with Windows Defender Security.
   • If the site looked like a tech support scam, it should also be reported using Microsoft’s scam reporting page.

What harm can come from it:

• Fake security notifications can trick users into allowing browser notifications, downloading unwanted software, or visiting malicious websites.
• Sites that aggressively open pop-ups and misleading buttons can be used to deliver malware or unwanted software.
• If nothing was clicked, downloaded, or allowed, the risk is usually limited to nuisance notifications.

How to remove it completely from the system:

• Remove the website notification permission in Edge.
• Clear cached browser data.
• Uninstall any recently added suspicious app from Settings > Apps > Apps & features.
• Review and remove suspicious browser add-ons if present.
• Run Microsoft Defender and review Protection history for any blocked or incomplete remediation events.

For ongoing protection:

• Keep Microsoft Defender SmartScreen turned on in Edge: Settings and more > Settings > Privacy, search, and services > Security > Microsoft Defender SmartScreen.
• Download software only from official websites or the Microsoft Store.
