What Is a Crypto Miner Virus?

A crypto miner virus, or cryptojacking malware, secretly uses a device’s CPU or GPU to mine cryptocurrency for an attacker, leading to increased electricity costs and potential hardware damage for the victim. It typically infects devices through phishing emails, pirated software, compromised websites, and malicious browser extensions. Monero is the preferred cryptocurrency for mining due to its efficiency on standard CPUs and privacy features. Signs of infection include overheating, high CPU usage, and increased electricity bills. Detection involves monitoring system performance and running antivirus scans. Prevention includes using antivirus software, keeping systems updated, and avoiding pirated software. Notable incidents include attacks on a European water utility and the Los Angeles Times website.

New Windows-native NVMe driver benchmarks reveal transformative performance gains, up to 64.89% — lightning-fast random reads and breakthrough CPU efficiency

Microsoft's native NVMe driver, initially released for Windows Server 2025, is now available for Windows 11, enhancing SSD performance. Users can achieve performance gains through registry tweaks. Benchmark tests showed significant improvements in random read bandwidth and input/output operations per second (IOPS). In a test with AMD EPYC 9754 processors and Solidigm P5316 SSDs, the following results were observed: - 4K Random Read: Non-Native Driver 6.1 GiB/s, Native Driver 10.058 GiB/s (+64.89%) - 64K Random Read: Non-Native Driver 74.291 GiB/s, Native Driver 91.165 GiB/s (+22.71%) - 64K Sequential Read: Non-Native Driver 35.596 GiB/s, Native Driver 35.623 GiB/s (+0.08%) - 128K Sequential Read: Non-Native Driver 86.791 GiB/s, Native Driver 92.562 GiB/s (+6.65%) - 64K Sequential Write: Non-Native Driver 44.67 GiB/s, Native Driver 50.087 GiB/s (+12.13%) - 128K Sequential Write: Non-Native Driver 50.477 GiB/s, Native Driver 50.079 GiB/s (-0.79%) Random read latency decreased significantly, with 4K and 64K read times dropping by 38.46% and 13.39%, respectively. However, 64K sequential write latency increased by 39.85%, while 128K sequential write latency rose by 12.43%. The NVMe driver also showed favorable CPU usage results during sequential read and write operations. It is not enabled by default in Windows 11, requiring users to make registry changes to activate it.

Windows Server 2025 Native NVMe: Storage Stack Overhaul and Benchmark Results

On December 15, 2025, Microsoft announced native NVMe support in Windows Server 2025, marking a significant evolution in data management and access. The new architecture replaces Disk.sys with NVMeDisk.sys, allowing direct communication from the filesystem to hardware via StorMQ, eliminating latency and enhancing performance. Testing revealed increased read speeds, particularly in random 4K and 64K benchmarks, with significant reductions in average read latency and lower CPU usage during sequential operations. Write operations showed modest improvements. A registry modification is required to enable this feature, and caution is advised due to potential complications with NVMe drives when deduplication is enabled.

Windows Update KB5077241 February 2026 Issues Nvidia GPU Bugs Task Manager Errors and ViVeTool Guide

Windows Update KB5077241, released in February 2026, is a 4.5GB feature update for the 24H2 and 25H2 versions. It poses significant performance risks for older hardware, particularly laptops and desktops without a Neural Processing Unit (NPU). Users with outdated Nvidia graphics cards, specifically the 900 Series (Maxwell) and 1000 Series (Pascal), report issues such as game stuttering, screen flickering, and system boot failures. The update also contains a flaw that inaccurately displays CPU usage in Task Manager, showing 0% utilization even under load. Many users face installation issues, encountering Error 0x800F0983, requiring them to delete update cache files and run repair tools. The update introduces features like a Taskbar Speed Test, Sysmon Security, improved Sleep/Wake functionality, and WebP wallpaper support, but many remain locked. Users can enable these features using ViVeTool with specific commands. Overall, the update is advised against for those with older Nvidia GPUs due to potential conflicts and performance issues.

Miss Windows 10’s movable taskbar? You still can’t relocate it in Windows 11, but new PowerToys feature could be the next best thing

A new menu bar concept is being considered for Windows 11 users, which could serve as an optional dock for the Command Palette within Microsoft's PowerToys suite. This feature aims to provide quick access to favorite tools and essential system-monitoring information. Windows 11 has faced criticism for not allowing the taskbar to be repositioned to the top of the screen, and the proposed top menu bar could offer a workaround. The Command Palette is envisioned as a future replacement for the Run utility, allowing users to launch applications and access utilities seamlessly. The dock could display information such as CPU usage and internet speeds, and users would have customization options for its appearance. While some users are concerned about losing desktop space, PowerToys allows users to choose whether to enable the Command Palette dock. There are suggestions that this dock could evolve into a full taskbar replacement, incorporating Windows 11 taskbar elements as widgets. PowerToys is designed as an add-on rather than a replacement for core Windows functionality. Microsoft is focusing on enhancing Windows 11, with hopes for user-requested features like taskbar repositioning.

Bitdefender and McAfee are both established antivirus solutions that achieve similar lab test scores, often earning 18 points in assessments by AV-Test and AV-Comparatives. Bitdefender offers a more economical pricing structure, with its Antivirus Plus plan priced between .99 and .99 per year for three devices, while McAfee's plans start at .99 for one device. In real-world malware protection tests, Bitdefender achieved a 99.8% protection rate, compared to McAfee's 99.3%. McAfee includes firewall protection at the antivirus level, while Bitdefender reserves its firewall for higher-tier plans but offers better exploit protection. Bitdefender successfully thwarted 11 out of 12 ransomware attacks in controlled tests, while McAfee's ransomware protection is less reliable. Both offer limited VPN services, with Bitdefender providing 200MB per day and McAfee offering between 250MB and 500MB per month. McAfee completes scans more quickly but uses more CPU, while Bitdefender is more thorough. Bitdefender includes additional security features like anti-tracker and secure browser, whereas McAfee's features are more limited.
