Microsoft Defender Crashes on Some PCs Due to Security Scan Issue

Microsoft's built-in security tool, Microsoft Defender, has been crashing on some PCs due to an issue affecting its ability to complete security scans. This leaves systems potentially vulnerable.

The problem was first flagged by user Huynh_Jovi on Reddit, where several users have reported issues with running scans using both Full Scan and Quick Scan modes.

A moderator in the thread has gathered key information on the situation, stating that the issue appears to be related to a Microsoft Security Intelligence update.

Performing an upgrade to Security Intelligence Update v1.457.236.0 resolves the issue, according to Reddit users Schoonie84 and Master_Pie1940.
