What The Tech: Beware of the anti-virus popup scam

A viewer experienced a pop-up warning claiming her device had 120 viruses, which is a scam designed to promote a free antivirus app called “Total Cleaner.” The pop-up aims to incite panic and persuade users to download the app, which has hidden costs, fake reviews, and privacy concerns. Modern smartphones generally do not require traditional antivirus programs, and these pop-ups are advertisements that do not reflect the phone's security status. To protect against such alerts, users should close the tab immediately, keep their device updated, and be cautious with app downloads.

RetroArch vs Lemuroid vs .emu: 127 Cores, $4.99 Each [2026]

As of August 2026, the main options for Android emulators include RetroArch, Lemuroid, and the .emu family of apps. RetroArch offers extensive system coverage and features, including netplay and rewind capabilities, but can be confusing for new users due to its multiple versions. Lemuroid is recognized for its simplicity and quick setup, making it ideal for beginners. The .emu family provides dedicated emulators for individual consoles, ensuring optimized performance but requiring a purchase for each app. RetroArch and Lemuroid are free, while the .emu apps cost around .99 CAD each. All three emulator options are legal, provided users supply their own BIOS files and ROMs. Devices with Snapdragon 660-class chips or newer are recommended for optimal performance across these emulators.

Beware of fake Indeed interview apps used to install spyware

Scammers are exploiting the Indeed platform to target job seekers by using counterfeit Android "interview" applications. Users in the UK and Brazil reported being instructed by supposed employers to download fraudulent apps like MyInterview, which compromised their devices. These scammers post fake job listings and prompt applicants to install apps that mimic Indeed's login page and establish a VPN connection. The malicious apps, classified as Trojan.Droppers, can install additional untrusted software and gain control over devices, complicating uninstallation efforts. Indeed confirmed that their interview process does not require downloading any separate app and warned job seekers against such scams. Indicators of compromise include specific MD5 hashes and package names associated with the Trojan droppers and dropped malware payloads.

Galaxy Store Will Start Hiding Unverified Android Apps in September

Samsung has alerted developers using the Galaxy Store about upcoming changes due to Google's new Android Developer Verification (ADV) rules, which will take effect on September 30, 2026. Developers in Brazil, Indonesia, Singapore, and Thailand must complete the verification process to avoid having their unverified apps removed from the Galaxy Store. The ADV process requires developers to authenticate their identities and register package names and signing certificates. Apps that are not verified will be hidden from search results and listings, affecting their visibility. Users may face difficulties reinstalling or updating existing apps until developers complete the verification, although previously installed apps will continue to function. Samsung is indicating the status of app binaries in the Seller Portal and will restrict new registrations and updates lacking ADV approval starting in September. Sideloading will still be possible for certain apps and through an advanced installation flow, while ADB installations will remain unchanged. The initial rollout is limited to specific countries, with a global expansion expected in 2027. Developers are encouraged to act quickly to maintain app visibility.

GBA Emulator Android: My Boy! vs John GBAC vs RetroArch

Game Boy Advance emulation on Android has gained significant traction in 2026, with key applications like My Boy! priced at .99, John GBAC receiving an update on May 19, 2026, and RetroArch enhancing its mGBA core for free use. The search term "gba emulator android" sees around 8,100 monthly searches in the U.S., reflecting a resurgence in interest, particularly among former GBA owners now in their late 20s and 30s who prefer using their smartphones for gaming. All five apps—My Boy!, GBA.emu, John GBAC, RetroArch, and Lemuroid—can run the entire GBA library at full speed on devices from the last six years. The main differences lie in software quality, including save state management, cheat code reliability, controller mapping, and update frequency. My Boy! and GBA.emu utilize cores derived from VisualBoyAdvance (VBA), while John GBAC uses a custom core, and RetroArch and Lemuroid rely on the mGBA core. In terms of features, all apps support save states, but My Boy! offers multiple named slots with thumbnail previews, while RetroArch has a more complex system. Cheat code support is available across the board, with My Boy! and GBA.emu accepting GameShark and CodeBreaker formats, and RetroArch providing a built-in cheat database. My Boy! stands out for its link-cable emulation, allowing local multiplayer connections, whereas RetroArch's netplay is designed for online gaming. All apps support external controllers, but RetroArch excels in visual enhancements with its extensive shader options. The setup process for all five apps is similar and typically takes under ten minutes. GBA ROMs are small, ranging from 4MB to 32MB, making them easy to store on modern devices without significant battery drain. Common issues include save files not loading, audio problems, and cheat codes failing to apply, with solutions often involving file management and settings adjustments. Users can migrate save files between emulators by ensuring the correct file naming and directory structure. Pros and cons of each app include: - My Boy!: Ad-free, strong multiplayer support, but lower rating and closed-source. - GBA.emu: High rating and broad support, but outdated and lacks a free trial. - John GBAC: Free and recently updated, but lower rating and ad-supported. - RetroArch: Free and feature-rich, but complex setup. - Lemuroid: User-friendly and actively maintained, but limited shader options. All five apps are legally available on Google Play, as they do not distribute copyrighted ROM files. Users are advised to source their ROMs legally, ideally by dumping from their own physical cartridges. GBA emulation remains an accessible entry point into retro gaming on Android, especially compared to more demanding systems like the PS2 or GameCube.

Migrate Vaultwarden to PostgreSQL: Scale for Teams [2026]

Self-hosting Vaultwarden with SQLite can lead to performance issues as the user base grows, particularly due to SQLite's limitations with concurrent writes. Transitioning to PostgreSQL allows for better performance, multi-user support, and enhanced data durability. PostgreSQL supports concurrent connections and row-level locking, making it more suitable for team environments. To migrate from SQLite to PostgreSQL, certain prerequisites must be met, including having an existing Vaultwarden deployment, Docker Engine, a PostgreSQL server, and pgloader installed. The migration process involves backing up existing data, deploying a PostgreSQL container, updating configuration files, and using pgloader to transfer data. A VPS with 2 vCPU and 4GB RAM can support up to 50 users, with larger teams requiring more resources. PostgreSQL also allows for the creation of organizations for shared vault access and the configuration of group policies for security. Regular backups and performance tuning are necessary to maintain optimal operation. Common pitfalls during migration include not stopping the Vaultwarden container before migration, failing to encode special characters in the database password, and neglecting to back up data. Troubleshooting may involve checking connection strings and ensuring the PostgreSQL container is healthy. Advanced configurations can enhance performance and functionality, and understanding the differences between Vaultwarden and Bitwarden's official self-hosted server can aid in decision-making.
