New Windows 10 security update proactively hunts down viruses when your PC is idle

Add as a preferred source on Google

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.

The size of a credit card: This fully functional computer even packs an e-ink screen
This credit card-sized computer packs Wi-Fi, NFC, and an e ink display
Muxcard

A developer has built a remarkably thin computer that is almost the same size and thickness as a standard credit card, potentially opening the door to a new category of ultra-portable computing devices.

Called the “Muxcard,” the experimental device combines a fully functional microcomputer, wireless connectivity, NFC support, sensors, and an E Ink display into a body measuring just 1mm thick - thin enough to fit inside a regular wallet alongside bank cards. The project, created by GitHub user “krauseler,” has quickly drawn attention from the maker and hardware enthusiast community for pushing the physical limits of compact electronics.

If your router or drone maker is banned in the US, it will get an update lifeline until 2029
Your “banned” router isn’t dead yet, says the FCC
Drone

The Federal Communications Commission has extended a key waiver allowing certain foreign-made routers, drones, and drone components to continue receiving software and firmware updates in the United States until at least January 1, 2029.

The move comes after growing concerns that millions of already-deployed devices could become cybersecurity risks if manufacturers were suddenly blocked from issuing security patches and compatibility updates. The decision was announced through the FCC’s Office of Engineering and Technology (OET), which also expanded the scope of the waiver to cover additional software-related changes needed to maintain device functionality.

AI-pilled graduates are not a big hit for finance jobs with their shallow ideas

Artificial Intelligence

Artificial intelligence may be transforming the financial industry, but some firms are beginning to push back against a growing trend: graduates who rely too heavily on AI tools without demonstrating deeper analytical thinking.

According to a report by The Financial Times, the issue recently surfaced through experiences shared by senior finance professionals, including one New York financier who described his company’s 2025 interns as the first group of “true AI natives.” These students had grown up using both digital platforms and generative AI systems, and initially appeared highly capable during recruitment.
