Microsoft has issued a signature update to fix a Windows Defender bug that caused 0xc0000005 access violations on some Windows 10 and Windows 11 systems.

Market Impact

The flaw triggered “Threat service has stopped. Restart it now” errors and crashed Defender during quick or full scans. System administrators said the crashes could be reproduced simply by initiating a Quick Scan on clean systems. Microsoft confirmed the issue and told BleepingComputer the fix is included in signature update version 1.457.236.0 or later.

“We have addressed this with a fix and recommend customers apply the latest update or enable automatic updates,” a Microsoft spokesperson said.

Microsoft said the update will apply automatically once the signature file is installed. Users are advised to run Windows Update, then check for the latest security intelligence update. Enabling automatic updates will ensure the fix is applied without delay.

Earlier this year, Windows Defender falsely flagged DigiCert root certificates as Trojan:Win32/Cerdigent.A!dha, causing widespread false positives and removing certificates from the Windows trust store.

In December 2025, a Microsoft Defender portal outage blocked access to Defender XDR portal capabilities and disrupted threat hunting alerts.

The Blue Report 2026, based on 338 million simulations, found that signature-based prevention fell to 50% once attackers gained valid credentials.
