How to Disable Copilot in Windows 11 — Uninstall, Hide, and Stop It from Coming Back

Microsoft has integrated its AI assistant, Copilot, into various parts of Windows 11, including the taskbar, Edge, and Notepad. Users have expressed a desire to remove Copilot, leading to the creation of a guide detailing methods to disable it. Copilot can be uninstalled through Settings, but additional steps are required to remove it from Edge, Notepad, and Windows Search. Users can also prevent Copilot from reinstalling after updates by adjusting registry settings. The Copilot app is categorized as a standalone application in Windows 11 24H2, making it easier to uninstall compared to previous versions. Methods to disable Copilot include: 1. Uninstalling the app via Settings. 2. Hiding the icon from the taskbar. 3. Using Group Policy Editor (limited to Pro, Enterprise, Education). 4. Removing Copilot for all users using PowerShell. 5. Adjusting settings in Edge and Notepad to disable Copilot features. 6. Editing the registry to remove Copilot from Windows Search and Paint. 7. Remapping the physical Copilot key on newer laptops. 8. Disabling silent reinstallation of Copilot through registry edits. Disabling Copilot will not affect core Windows functionality but will remove AI-specific features such as the chatbot and writing assistance.

Researchers Discover First Android Malware Using Generative AI for Persistence

Security researchers have identified a new Android Trojan named PromptSpy that uses generative AI technology to enhance its persistence on compromised devices. Discovered by ESET researchers, PromptSpy leverages Google's Gemini AI model to analyze infected device screens and generate tailored instructions for embedding itself within recent apps lists. It includes a Virtual Network Computing (VNC) module that allows attackers full remote control over the device, enabling activities such as viewing the screen, performing actions remotely, capturing lock screen data, blocking uninstallation attempts, gathering device information, taking screenshots, and recording screen activity as video. The malware communicates with command-and-control servers using AES encryption and exploits Android Accessibility Services, making it difficult to remove. PromptSpy is distributed through a dedicated website and is financially motivated, adapting to various Android interfaces and operating system versions. ESET's analysis indicates that the malware is regionally targeted, with a focus on Argentina, and may have been developed in a Chinese-speaking environment. The same threat actor is believed to be responsible for both VNCSpy and PromptSpy.

PromptSpy Android Malware Abuses Google Gemini to Automate Recent-Apps Persistence

Cybersecurity researchers have identified a new Android malware named PromptSpy that utilizes Google's Gemini AI chatbot to enhance its capabilities and persistence on infected devices. PromptSpy can capture lockscreen data, obstruct uninstallation, gather device information, take screenshots, and record screen activity. It integrates Gemini to analyze the current screen and provide instructions to keep the malware active in the recent apps list. The malware uses a hard-coded AI model and communicates with a command-and-control server via the VNC protocol, allowing remote access to the victim's device. It is financially motivated, targeting users in Argentina, and was developed in a Chinese-speaking environment. PromptSpy is distributed through a dedicated website and is considered an advanced version of a previously unidentified malware called VNCSpy.

How to Install McAfee Antivirus on Windows 11 or 10

Installing third-party antivirus software like McAfee on Windows 11 can be challenging due to the built-in Windows Security, which can complicate the installation process. Users may face issues such as silent failures from conflicting software, permission problems on restricted machines, or restrictions due to S Mode on new laptops. Windows 11 includes Windows Security, which is effective for malware protection, but McAfee may be necessary for compliance, additional features, or centralized protection for multiple devices. McAfee supports Windows 11 Home, Pro, and Education editions but not Enterprise. The minimum hardware requirements include a processor of 1 GHz or faster, at least 2 GB of RAM (4 GB recommended), 1.3 GB of free disk space, an internet connection for download and updates, and a display resolution of at least 1024×768. McAfee requires a persistent internet connection for activation and updates. Before installing McAfee, users should check if their device is in S Mode, as McAfee cannot be installed in this mode. They must remove any existing antivirus software completely, as leftover files can interfere with the installation. Users should also ensure that Windows 11 is up to date and verify that there is enough disk space available. To download McAfee, users should go directly to the McAfee trial page to avoid scams. After downloading, they need to run the installer and restart their computer after installation. Users should then activate McAfee, run a manual update, and conduct a full system scan. Common installation problems include freezes during download, errors due to S Mode, and issues with Windows Security not recognizing McAfee as the active antivirus. Users can verify that McAfee is functioning correctly by checking the system tray icon, Windows Security settings, and the McAfee dashboard. To uninstall McAfee, users should go to Settings > Apps > Installed Apps, select McAfee, and follow the prompts to remove it. After uninstallation, Windows Security will reactivate automatically. McAfee offers several plans for Windows users, including Basic, Essential, Premium, and Advanced, each with different features and device limits. The Basic plan is suitable for single-device users without additional needs, while families may benefit from the Essential or Premium plans.

Copilot Uninstall Lands On Managed Windows But With Catches

IT administrators can now uninstall the Microsoft Copilot app from managed Windows devices under specific conditions. This option is available only for devices running an Insider Preview of Windows 11 and is designed for Enterprise, Pro, and Education editions. The Group Policy named RemoveMicrosoftCopilotApp allows this uninstallation, but it requires that the Microsoft 365 Copilot and the Microsoft Copilot app are installed, the app must not have been user-installed, and it must remain unopened for 28 days. The policy aims to prevent accidental removals and ensure organizations consider the app's deprecation thoughtfully. For unmanaged PCs, users can hide the Copilot button and disable it in Startup Apps to minimize its presence, but a straightforward uninstallation method is not yet available.
