Install The latest Windows Defender Update To Fix Broken Windows Defender Scanning Feature

It seems like September patch Tuesday updates have become a nightmare for Windows 10 users. These updates introduced a number of new bugs including the infamous Start menu bug. Moreover, some other users experienced Network adapter failures in some cases.

Apparently, the series of issues is not over yet and this time the update breaks Windows Defender. According to some forum reports, a recent security update has affected the manual search capabilities of Windows Defender. The update was basically released to patch a bug that forced Windows Defender to display the following error message during the execution of SFC /scannow command.

Windows Resource Protection found corrupt files but was unable to fix some of them.

Although Microsoft rolled out Windows Defender version 4.18.1908.7 to fix the issue. However, the update brings a new bug of its own. Those who tried to use the Quick and Full antivirus scan feature of Windows Defender reported that the capability is restricted to just 40 files.

Thankfully, the bug didn’t break Windows Defender’s real-time protection and it only affected the above-mentioned functionality.

How To Fix Windows Defender Scanning Bug?

Fortunately, Microsoft confirmed the issue and the tech giant immediately rolled out a patch to fix it. The company titled the update as Security Intelligence Update for Windows Defender Antivirus. Those who are experiencing a similar problem should install Windows Defender version 1.301.1684.0 to resolve the scanning bug.

Microsoft Defender AV employs real-time scanning of endpoints, which was not impacted by this update. Only manual or scheduled scans conducted by administrators were temporarily impacted and we are working to resolve it.

The update should be available automatically on your systems. However, Microsoft recommends its users that they should navigate to the Windows Security Virus & Threat Protection section to check for updates. Here is how you can do that.

  1. Type Windows Security in the search box available in the Taskbar.
  2. Select Virus & threat protection and then click Check for updates option.

Most Windows users around the world rely on Windows Defender for the protection of their systems and Microsoft already has a bad rep for releasing buggy updates for Windows 10.
