Windows Defender malware scans are failing after a few seconds
The latest version of Windows Defender, the built-in anti-malware solution of Windows 10, is affected by a bug that causes Quick or Full scans to stop running after inspecting only a few files. The flaw is the result of a recent patch issued by Microsoft to solve another issue. It impacts not only Windows 10 systems but also all other operating systems running Windows Defender.
Microsoft has acknowledged the issue and is currently developing a patch. The tech giant stresses that only manual and scheduled Quick or Full scans are affected. Real-time scanning still works and users can avoid the issue in manual and scheduled scans be choosing the “Custom scan” option instead or a Quick or Full scan.
