The Point-in-Time Restore feature in Windows 11 allows users to revert their system to a previous state, but it may result in the loss of recently created files. This feature captures the system's state, including Windows system files, installed applications, and local settings. Restore points are generated automatically every 24 hours, but users can create them manually. However, restoring can erase new documents, recently installed applications, and any settings changes made since the last restore point. Files stored in OneDrive remain unaffected. To verify Point-in-Time Restore settings, users must access the Settings application, select System, and then Recovery. Restore points are retained for up to 72 hours and may be deleted sooner if storage is limited. Windows 11 version 26H2 enables this feature by default for devices with an OS volume of at least 200 GB. Before restoring, users should back up recent work to an external drive. To initiate the restore, access the Windows Recovery Environment, select Troubleshoot, and then Point-in-Time Restore. If files are lost after a restore, 4DDiG Data Recovery Software can help recover deleted files. It scans local drives for files deleted during a rollback or accidental deletion. A robust recovery plan should include using Point-in-Time Restore, OneDrive for daily file protection, and separate backups before significant system changes.

A new tool named BigDiskBuster has been released on GitHub, which disrupts Microsoft Defender Antivirus by preventing it from installing updates. It does this by consuming available disk space during the update process, causing Defender to remain on its current version and unable to receive new platform or signature updates. BigDiskBuster operates as a local denial-of-service technique and requires prior access to the target machine to execute. The tool was created by researcher Abdelhamid Naceri, known as Nightmare Eclipse, who has previously worked on similar projects. As of now, there is no CVE identifier, patch, or advisory from Microsoft regarding this issue.

The landscape of computer security has changed significantly over the past two decades. In 2026, antivirus protection remains important, but the need for separate third-party programs has decreased for many users due to the built-in Microsoft Defender in Windows 11, which is activated by default and effectively blocks 100% of common malware samples according to independent testing by AV-TEST. Windows 11 also includes additional protective features like SmartScreen and a robust Firewall. While dedicated security suites from companies like Norton and Bitdefender offer advanced functionalities, many users may find adequate protection with the built-in tools. Research from AV-Comparatives indicates that performance varies among security programs, particularly against real-world attacks. Phishing attacks accounted for approximately 60% of initial access points in incidents examined by the ENISA Threat Landscape report from 2025, highlighting that user behavior is a significant vulnerability. Modern web browsers and operating systems have enhanced their security measures, with Google Chrome, Microsoft Edge, macOS, and Android incorporating features to protect users from harmful websites and downloads. For the average Windows 11 user who keeps their system updated and practices safe browsing, built-in protection is generally sufficient, though paid antivirus options can provide additional tools.

More than 5,400 websites across over 2,200 organizations have been compromised to propagate malware, primarily affecting small businesses like clinics and online retailers. The attack mechanism involves malicious code that triggers a deceptive CAPTCHA, instructing users to execute commands that can download malware. Attackers are using the BNB Smart Chain test network to store instructions, making it harder for investigators to shut down operations. A newer variant of the attack uses WebRTC technology to establish encrypted connections for delivering additional malicious code. To protect against these threats, users should avoid pasting commands from websites, be suspicious of unusual CAPTCHA instructions, use strong antivirus protection, keep systems updated, take action if commands are executed, and small business owners should regularly verify their website's integrity.

For nearly two months, Windows 11 users received persistent notifications from the Windows Security app falsely indicating that Microsoft Defender was disabled, despite it functioning properly. This issue, which began in early August, has been addressed with a security update from Microsoft. The false alerts affected all versions of Windows 11, Windows Server, and Windows 10, and were linked to a bug introduced with a recent Defender security update. Microsoft confirmed that no manual action is required from users to resolve the issue, as the fix will be automatically deployed to all PCs with mandatory security updates enabled. The problem was resolved in the Microsoft Defender Antivirus update (version 4.18.26080.4), released on September 17, 2026. Users can verify the status of Defender by checking Windows Security or using a PowerShell command.
