How to Stop McAfee from Running on Windows

McAfee offers features such as file scanning, network traffic filtering, VPN services, and browser warnings to protect users. Users can pause Real-Time Scanning by opening the McAfee app, selecting Real-Time Scanning under My Protection Widgets, and turning it off. To disable the Advanced Firewall, users must access the Advanced Firewall section in the app and turn it off. Scheduled scans can be stopped by navigating to Scheduled Scans in the app and clicking Turn off. To prevent Secure VPN from reconnecting, users can toggle it off in the Home tab and set Auto Connect to Never connect automatically. Browser protection features can be managed by toggling off McAfee WebAdvisor in Chrome, Edge, and Firefox. Users can block fake McAfee popups by adjusting notification settings in their browsers. To prevent McAfee startup helpers from opening, users can manage startup settings in Windows. To completely remove McAfee, users should uninstall it through Settings or Control Panel and follow the prompts. If remnants remain, the MCPR tool can be used for complete removal. Microsoft Defender will reactivate automatically after McAfee is uninstalled.

Messenger Interoperability: Well-Intended, but Bad for Data Privacy

WhatsApp began supporting third-party messaging services in late 2025 in compliance with the EU's Digital Markets Act (DMA), which requires major tech companies to enable interoperability with alternative chat platforms. Threema has chosen not to implement interoperability with WhatsApp, citing concerns over user privacy and security, as differences in user identification methods could lead to compromises that weaken privacy protections. Threema believes that interoperability could reinforce WhatsApp's market dominance, reducing the incentive for users to adopt the Threema app. Additionally, Threema's business model relies on app sales for revenue, and a drop in downloads due to interoperability could threaten this model. Consequently, Threema has decided against pursuing interoperability with WhatsApp to maintain its commitment to privacy and security.

Google Play Store update ensures you don’t forget about widgets from that shiny new app

Google has updated its Play Services to version 26.28, allowing users to display their device's IMEI number on the lock screen, which can aid in device recovery but may pose security risks. This feature is server-side and may not be available on all devices immediately. Other enhancements include audio permission requests in WebViews, Android Credential Manager support for Android TV, and various quality-of-life improvements. The Play Store has been updated to version 52.4, introducing natural language queries for search, expanded search suggestions, limited mobile data usage for app restoration in India, Nigeria, and Indonesia, and the option to add app widgets during installation. Users can update their Google System Services through their device settings.

Google and Epic Abandon Settlement, Clearing the Way for Rival Android App Stores

Google and Epic Games have withdrawn their joint motion to modify a court injunction that requires Google to support third-party app stores within the Google Play ecosystem. A permanent injunction issued in October 2024 mandates Google to facilitate alternative app stores on Android devices, with support set to begin on July 22. Google plans to implement a ,000 annual access fee for these alternative marketplaces, while apps downloaded through these stores will still use the Google Play system for transactions. The agreement between Google and Epic includes provisions for reduced fees and alternative payment methods, separate from the injunction. The legal situation regarding third-party app stores does not directly affect Apple, but it may influence Apple's ongoing legal challenges with Epic Games and regulatory developments. Apple is currently appealing a ruling that requires it to allow link-outs and alternative payment options, with oral arguments expected in late 2026 or early 2027.

Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.

Microsoft Confirms Windows GDID Device Identifier That Cannot Be Disabled, Documented in FBI Case Filing

Microsoft has confirmed the existence of the Global Device Identifier (GDID), a unique identifier assigned to Windows installations, in a federal complaint against an alleged member of the Scattered Spider hacking group. The GDID is generated when a Windows system is set up with a Microsoft Account and remains active through various Windows updates. Disabling the GDID could disrupt Windows activation and access to Microsoft Store applications. The GDID is described as "a persistent, device-level identifier designed to uniquely identify an installation of a Windows operating system on a device." It is created during the provisioning of Windows with a Microsoft Account and is stored in the Windows registry under HKCUSOFTWAREMicrosoftIdentityCRLExtendedProperties. The GDID remains persistent through Windows updates but is not retained after a clean reinstall. A single user can possess multiple GDIDs linked through their account, OneDrive, and activation history. The FBI used the GDID to track Peter Stokes, an alleged member of the Scattered Spider group, across various VPN connections and proxy servers. The GDID was recorded visiting specific websites and was linked to Stokes's accounts on platforms like Snapchat and Facebook. Concerns have been raised regarding user privacy, as the GDID is assigned without user consent and cannot be disabled without compromising essential Windows features. Microsoft has not committed to providing user-facing controls or comprehensive documentation for everyday users regarding the GDID. Legal requests can compel Microsoft to disclose GDID activity data to law enforcement. The GDID is linked to the Microsoft Account rather than the device itself, meaning reinstalling the operating system does not sever this connection.

Study of 281 Free Android VPN Apps Finds Traffic Leaks, Unencrypted Data, and Tracking

Researchers analyzed 281 popular free VPN applications on the Google Play Store and found significant privacy and security shortcomings. The study, conducted by teams from the University of Michigan, the University of New Mexico, and IIT Delhi using a framework called MVPNalyzer, revealed that flagged apps had over 2.4 billion downloads. Key findings included: - Five apps transmitted configuration files unencrypted, allowing attackers to intercept and modify them. - 29 apps allowed user traffic to leak outside the encrypted tunnel, with 24 leaking DNS traffic and six leaking full browsing traffic. - 169 apps made no effort to disguise their traffic, making it identifiable to network operators or government censors. - 76 apps transmitted the device's Advertising ID to advertisers, and over 80% contacted known advertising and tracking servers. - Only one of 108 OpenVPN configurations adhered to recommended security practices; 89% used a single authentication method, and nearly 20% employed outdated encryption techniques. - Many apps passed through Play Store checks without adequate scrutiny, with safety labels often serving as marketing tools rather than security indicators. These findings align with previous research highlighting similar issues in popular Android VPN apps. Users are advised to be cautious when selecting VPNs, prioritizing those with recent independent security audits.

How to Use a Virus Checker on Your PC (2026)

Windows includes a built-in virus checker called Microsoft Defender Antivirus, which allows users to conduct virus scans. 1. To initiate a scan, open Windows Security, navigate to Virus & threat protection, and select Quick scan for a fast check. 2. Users can check which antivirus is active by going to Who's protecting me? in Windows Security. If a non-Microsoft antivirus is installed, Microsoft Defender will disable itself. 3. Before scanning, it's important to update the security intelligence by checking for updates in Protection updates. 4. A full scan can be executed by selecting Full scan in Scan options, while a custom scan allows users to specify a location to check. 5. For stubborn malware, Microsoft Defender Offline can be used, which requires a restart of Windows. 6. Scan results and quarantined threats can be reviewed in Protection history after any scan. 7. For additional checks, users can utilize VirusTotal for individual files or links, Microsoft Safety Scanner for a one-time scan, or the Malicious Software Removal Tool for specific malware. 8. Outdated tools like the Chrome Cleanup Tool and Norton Power Eraser should be disregarded as they are no longer effective. Users can scan individual files without scanning the entire PC, and results from the Microsoft Defender Offline scan are found in Protection history. The Microsoft Safety Scanner does not replace real-time antivirus protection, and managed devices can be scanned by IT administrators.
