30-year Microsoft veteran explains why you shouldn’t run two antivirus apps on Windows 11

Raymond Chen, a Microsoft veteran, advises against installing multiple antivirus solutions on the same system due to conflicts that arise, such as each program attempting to quarantine the other's processes. This can lead to significant performance issues and erratic behavior in Windows. Microsoft has stated that Windows Defender is sufficient for most users, highlighting its comprehensive security features in Windows 11. The company warns that running multiple real-time antivirus programs can increase resource consumption and conflict likelihood. Independent testing has shown that Microsoft Defender ranks highly among antivirus solutions.

OM SDK sandbox cuts Android ad session start to 11 ms, IAB Tech Lab says

IAB Tech Lab has released version 1.6.10 of its Open Measurement SDK for Android, introducing the ability for verification scripts for native ads to run within Android's Jetpack JavaScriptEngine instead of the traditional WebView. This update, effective from October 1, 2026, allows for a significant reduction in verification check initiation time, with the sandbox environment taking approximately 11 milliseconds compared to 268 milliseconds in the WebView. Applications that do not implement this new feature will continue to function as before, and HTML-based ads are not included in this update. The JavaScriptEngine library allows JavaScript evaluation without a WebView, reducing resource consumption and enabling compatibility with background services. The adoption process for this feature involves updating to OM SDK Android 1.6.10 or later, integrating the androidx.javascriptengine dependency, and maintaining the sandbox throughout the app's lifecycle.

Does antivirus software still slow down your PC in 2026? We tested the top security software to find out

Modern antivirus solutions have evolved to integrate seamlessly into daily computing without causing slowdowns, allowing users to maintain speed while ensuring security. Contemporary antivirus software utilizes behavioral analysis and cloud-based threat intelligence to minimize resource consumption during scans. Recent testing assessed the impact of various antivirus suites on gaming performance and internet speeds, revealing that Bitdefender had negligible drops in download and upload speeds during scans, while Malwarebytes showed a significant decline in upload performance. Avast experienced the most considerable degradation in download speeds, and McAfee unexpectedly increased upload speeds during scans. Overall, advancements in antivirus technology mean that running security software no longer requires sacrificing performance.

These 3 popular Windows apps run faster as CLI tools: Here’s how to switch

Windows provides graphical tools for various tasks, but terminal commands can be more efficient. Three utilities that serve as alternatives to File Explorer, Task Manager, and Notepad are zoxide, btop, and bat, all of which can be installed using winget. zoxide is a directory jumper that simplifies navigation through folder structures by learning user habits. It can be installed with PLACEHOLDERf0ff8219c0950297 and requires a line added to the PowerShell profile for activation. Users can jump to directories by typing PLACEHOLDERb9546a80b5ad16aa followed by part of the folder name, and it adapts over time based on usage patterns. btop is a system monitor that displays processor, memory, disk, network, and process data on a single terminal screen. The Windows version, btop4win, can be installed with winget install aristocratos.btop4win. It features live graphs, allows navigation via keyboard and mouse, and provides real-time updates on resource consumption. Users can filter and sort processes and terminate them directly from the interface. bat is a command-line file viewer that shows file contents with syntax highlighting and line numbers, eliminating the need to open Notepad. It can be installed using winget install sharkdp.bat and allows users to view files directly in the terminal. It integrates with Git to highlight changes and manages longer files with a pager for easier scrolling. These tools enhance efficiency for common tasks in Windows by providing quick access and streamlined workflows through the terminal.

My 4-year-old Android phone is showing its age. Here’s how I’m keeping it running

Many users are considering whether to upgrade their smartphones or extend the life of their current devices. Strategies to rejuvenate aging smartphones include: 1. Replacing Hardware: Replacing the battery can significantly improve performance, especially if the original battery's health is below 75%. Using a slower charger (like an 18W charger) can reduce heat and extend battery longevity. 2. Switching Apps: Replacing resource-heavy applications with lighter alternatives can enhance performance. For example, using the Brave browser instead of Chrome and AntennaPod instead of Spotify can conserve battery life. 3. Optimizing System Settings: Adjusting settings such as window animations and screen refresh rates can improve user interface responsiveness. Setting a maximum charge limit of 80-90% can help mitigate heat buildup. 4. Regular Maintenance: Deleting large files and using Android's built-in Private DNS can prevent lag and enhance performance. Flashing a custom ROM like LineageOS can provide a new operating system experience but may come with risks. 5. User Vigilance: While older phones may pose security risks, users can extend their life with regular updates and maintenance, especially as manufacturers offer devices with longer software support.

“Iran unveils second homegrown antivirus to counter malware and cyberattacks”

Iran has introduced its second domestically developed antivirus software, Ayyza, which utilizes artificial intelligence and machine learning to detect known and unknown cyber threats. The antivirus is designed to protect against malware, viruses, Trojans, ransomware, and advanced persistent threats (APTs). Ayyza's detection engine is developed in-house and operates at the Windows kernel level to enhance detection accuracy and speed while minimizing hardware resource consumption. It can receive updates offline or via Iran’s National Information Network. Ayyza's machine-learning capabilities allow it to identify emerging threats, including previously unknown malware and zero-day vulnerabilities. The company has also created complementary security tools, such as privileged access management (PAM) systems and data leakage prevention tools, to enhance overall cybersecurity. The company's products are currently used in various Iranian infrastructures, including banking, financial, and governmental systems.
DLSS 5 can be jammed into almost any game now, so I've been playing FM26 with neural rendered little computer people because that's just what I do

DLSS 5 can be jammed into almost any game now, so I’ve been playing FM26 with neural rendered little computer people because that’s just what I do

The integration of DLSS 5 .dll files into various games has produced mixed results, with some enhancements working well while others cause visual glitches. A review of The Blood of Dawnwalker revealed issues with the DLSS pipeline, resulting in an unexpected undead appearance for a character. A demonstration at Gamescom showed that DLSS 5 can significantly enhance visuals when used correctly, particularly with Model C at 60-70% intensity. However, Nvidia has noted that DLSS 5 can lead to a 50-60% reduction in frame rates, especially at 4K resolution. For example, on an RTX 5090, frame rates dropped from approximately 110 fps to below 50 fps with DLSS 5 activated. DLSS 5 can also run on lower-spec GPUs, although it was initially demonstrated with dual RTX 5090s. In Football Manager 26, DLSS 5 improved visuals without achieving photorealism, maintaining a steady 60 fps. The ReShade HDR Installer allows users to integrate DLSS tools into unsupported games, but results may vary and troubleshooting may be necessary. The official release of DLSS 5 will not include the fine-tuning sliders available through ReShade, which could complicate the preservation of developers' artistic intent. For best results, users should use the Upscaled or DLSS version of DLSS-NR rather than the 'Present' method, and may need to try different RenoDX DLSS 5 tools if issues arise.
