MuMu Player vs GameLoop vs KOPLAYER: Android 15 Gap

Android emulators for PC have become a crowded market with close to a dozen actively maintained clients. Tencent and NetEase have first-party products like GameLoop and MuMu Player to control the PC on-ramp to their mobile catalogs. Independent players like BlueStacks and LDPlayer focus on platform-agnostic performance and feature breadth. KOPLAYER appears to be abandoned in 2026 with no updates, functioning website, or active development. MuMu Player supports Android 15, offering newer features for mobile games. GameLoop is focused on Tencent's mobile titles with updated documentation. MuMu Player and GameLoop are free, while KOPLAYER is also historically free. MuMu Player and GameLoop have ongoing updates and security, while KOPLAYER's lack of updates poses a security risk.

Windows 11 is getting a better way to find your mouse cursor, and we tried it

Microsoft has released a modernized version of the Mouse Indicator in Windows 11 Insider Preview Build 26340.9502 on September 18, 2026.

Google’s Android Bench 2.0 tests AI agents on week-long app builds

Google has launched Android Bench 2.0, an upgraded benchmark for evaluating AI coding agents, which now includes 30 long-horizon tasks that can take human engineers days or weeks to complete. The best pass rate for these tasks is around 28%, down from approximately 91% in the previous version. The benchmark measures both pass rates and completion rates, acknowledging partial progress rather than just failures. It assesses various challenges, including app creation and feature integration, using a comprehensive scoring methodology that evaluates functionality, regression checks, and visual fidelity. AI models perform better with new code than with modifications to existing systems, facing challenges in runtime validation and cross-platform conversions. The current leaderboard shows OpenAI’s GPT-6 Astra leading with a 28% pass rate, while Gemini 3.8 Flash has an 8% pass rate. Developers using AI agents should be aware that while AI can generate significant portions of applications, further refinements will require human input. The benchmark is available on Google’s Android Bench leaderboard.

Set Up Bitdefender Antivirus Free: 13 Steps [2026]

Bitdefender Antivirus Free was upgraded to version 27.0.62.355 on September 11, 2026, introducing a new Advanced Threat Defense driver that enhances behavioral monitoring capabilities. The free version is designed for Windows only and promises to remain free indefinitely, lacking features found in paid versions such as anti-tracking tools and a full vulnerability scanner. The installation requires Windows 10 or 11, at least 2GB of free disk space, a local administrator account, an active internet connection, and a Bitdefender Central account. Users must remove any existing antivirus software before installation, and the installation process typically takes 60 to 75 minutes. Bitdefender Free covers one Windows device and offers robust malware detection capabilities, particularly with the Advanced Threat Defense layer. It is recommended to schedule regular scans and check the Notification Center for quarantined items. If uninstalled, the dedicated uninstall tool should be used to avoid leftovers that could interfere with future installations.

The feature, previously known as NotebookLM, is now part of the main Gemini interface, allowing users to create interactive learning materials, reports, and slide decks. Workspace administrators can control access to the feature, which must be enabled at the organizational level. Users in the European Economic Area (EEA) do not have access to this feature due to regional restrictions on artificial intelligence applications.

Hackers Disguise CHOSEN BRICK Malware as AI Apps, Antivirus Software and MRI Results

Iranian state-affiliated cyber actors are targeting dissidents, activists, and journalists using fake AI applications, counterfeit antivirus tools, and fabricated MRI scan results, primarily through a spyware family known as CHOSEN BRICK, which is designed for Windows systems. This campaign has been active since at least 2025 and affects individuals globally, including in the UK, US, and Netherlands. The malware establishes persistence via the Windows Registry Run key and communicates through Telegram, utilizing unique Bot IDs for each victim. CHOSEN BRICK is capable of extensive data collection, including capturing screenshots, recording audio, and stealing email content. Personal information from victims has been found on pro-Iranian leak sites, increasing harassment risks. Security measures should include monitoring for suspicious Registry entries and unusual communications, while users are advised to avoid unsolicited software installations and keep their systems updated. The FBI refers to this malware family as HEAVYGRAM.
