Windows 10 is building in an additional line of defense against malware with some new features for Windows Defender, Microsoft’s pre-installed antivirus.

The update is called Limited Periodic Scanning, and was revealed as part of Microsoft’s Insider Preview Build 14352 this week. It allows users to run Windows Defender simultaneously to their own antivirus software. Defender will run its own periodic scan of your computer to further bolster the protections in place with other programs.

If the feature catches any malware you’ll be notified through a standard Windows 10 notification but in most cases, Windows Defender will act automatically on mitigating the malware in the background.

Limited Periodic Scanning, in theory, will only kickstart when your computer is idle or not in the middle of some important task. It uses the Automatic Maintenance feature to select the most opportune time to scan, according to the announcement.

There have been a number of complaints against Microsoft over Windows 10 updates commencing in the middle of important work so the company will want to avoid such a fate again.

Limited Periodic Scanning is only for use by consumers so far, said Deepak Manohar from Microsoft Malware Protection Center, but the company is exploring possible enterprise applications for the feature.

The feature is currently only available for Windows Insiders and is turned off by default if you’re not already using Windows Defender. To turn on Limited Periodic Scanning, go to Settings, Update & Security and Windows Defender, and then Turn Limited Periodic Scanning on.

Microsoft has placed a big emphasis on security for Windows 10, claiming it is the most secure operating system available on the market right now. The CIO of the Pentagon, Terry Halvorsen has even publicly gushed over the security of the OS and urged his employees to use it on their personal devices. However, Windows 10 has still faced many concerns and criticisms over its attitude to user privacy by collecting and monitoring a huge amount of data.

There’s a scary new way to undo Windows security patches

Security patches for Windows are essential for keeping your PC safe from developing threats. But downgrade attacks are a way of sidestepping Microsoft's patches, and a security researcher set out to show just how fatal these can be.

SafeBreach security researcher Alon Leviev mentioned in a company blog post that they'd created something called the Windows Downdate tool as a proof-of concept. The tool crafts persistent and irreversible downgrades on Windows Server systems and Windows 10 and 11 components.

Microsoft may be rolling out a new feature as part of the latest Windows 11 update that will boost security but slow down SSD performance. We're talking about BitLocker, of course, a device encryption feature that will be turned on by default as part of the upcoming 24H2 update.

In the past, BitLocker encryption was available only on Windows Pro editions, but the new update lowers the eligibility criteria, extending encryption capabilities to a broader range of devices.

Microsoft has issued security updates to address 90 vulnerabilities, some of which hackers are actively exploiting, in a blog post yesterday. These flaws allow hackers to bypass security features and gain unauthorized access to your PC's system, highlighting the need to keep your Windows computer updated.

Nine are rated Critical, 80 of the flaws are rated Important, and only one is rated Moderate in severity. In addition, the software giant has patched 36 vulnerabilities in its Edge browser in the past month to avoid issues with its browser. Users will be happy to know that the patches are for six actively exploited zero-days, including CVE-2024-38213. This lets attackers bypass SmartScreen protections but requires the user to open a malicious file. TrendMicro's Peter Girnus, who discovered and reported the flaw, proposed it could be a workaround for CVE-2023-36025 or CVE-2024-21412 that DarkGate malware operators misused.
