ClamAV Setup: Linux Antivirus in 12 Steps [2026]

Malware can threaten Linux systems, which are often mistakenly believed to be immune to viruses. It can be introduced through email attachments, infected files, or compromised plugins, especially when Linux servers interact with Windows clients or handle internet uploads. ClamAV is an open-source antivirus engine maintained by Cisco Talos, designed for scanning mail traffic and file uploads. As of mid-2026, the stable release is ClamAV 1.5.x, with version 1.5.2 being the latest patch. To deploy ClamAV, users need root or sudo access on a compatible Linux machine, at least 2 vCPUs and 2GB of RAM, 5GB of free disk space, and outbound HTTPS access to ClamAV’s signature mirrors. The installation process involves several steps, including configuring freshclam for automatic updates, validating detection with the EICAR test file, and setting up cron jobs for regular scans. ClamAV can also be integrated with mail servers and a SIEM for enhanced security. Common pitfalls in deployment include skipping the initial freshclam run and using clamscan instead of clamdscan for repeated scans. ClamAV is free for commercial use and can also scan Windows systems, although it does not replace comprehensive endpoint protection solutions.

Migrate self-managed PostgreSQL to Amazon RDS using the RDS console

Running PostgreSQL on Amazon EC2 requires users to manage operational tasks such as patching, backups, and security. Migrating to Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible Edition offers a fully managed service that automates these tasks, allowing development teams to focus on application development. The migration process uses the auto-migration feature in the Amazon RDS console, supported by AWS Database Migration Service (AWS DMS), which facilitates PostgreSQL-to-PostgreSQL migrations using native tools for accurate schema mapping and faster migration. The migration can be executed using various methods, including pg_dump/pg_restore, manual AWS DMS tasks, or third-party tools, with the RDS console approach being preferred for its reliability and minimal setup effort. AWS DMS supports three replication modes: full load, CDC only, and full load + CDC, with the migration duration depending on database size and network throughput. Prerequisites for migration include having a source PostgreSQL 10.4+ on Amazon EC2, a target RDS for PostgreSQL or Aurora PostgreSQL, proper IAM roles, stored credentials in Secrets Manager, and appropriate networking configurations. Considerations include unsupported objects, potential issues with sequence values, and the need to avoid schema changes during CDC. The migration involves preparing the source database, creating necessary users and permissions, and executing the migration through the RDS console. Post-migration, it is essential to verify data integrity, optimize performance by updating statistics and rebuilding indexes, and implement security best practices such as disabling the DMS user and enforcing SSL/TLS connections. Common troubleshooting errors during migration include permission issues, incorrect WAL levels, and connection refusals, each with specific resolutions. Finally, to avoid ongoing charges, it is recommended to clean up resources created during the migration process, including deleting the DMS migration task, logical replication publications, Secrets Manager secrets, and the target RDS/Aurora instance.

Xbox console players now get select Ubisoft PC versions for free via Xbox PC — it’s not Xbox Play Anywhere, but hey it’s something

Ubisoft and Microsoft have announced an extended collaboration that will allow owners of select Ubisoft titles on Xbox Series X|S to gain complimentary access to their PC counterparts, excluding those who purchased games through the Xbox PC store. Ubisoft has added over 80 games to the Xbox PC store, many of which are part of the Ubisoft+ Classics lineup included with Xbox Game Pass Ultimate. However, the Ubisoft Connect PC app has faced criticism for its reliability, and while some games feature progression syncing between PC and Xbox consoles, it often does not match the functionality of Xbox's Play Anywhere feature. Many gamers express frustration over Ubisoft's lack of integration of key Xbox features into their PC games.

How to Use WorldEdit in Minecraft Java and Bedrock

WorldEdit is a tool for Minecraft that has different requirements for Java Edition and Bedrock Edition. Users must select the correct version for their Minecraft edition. For Java Edition, WorldEdit can be downloaded from EngineHub or Modrinth, while Bedrock Edition requires a separate add-on. To install WorldEdit on Java Edition, users need to download the appropriate .jar file and place it in the server's plugins or mods folder, depending on the platform. Command access must be granted based on world or server settings, and users can select blocks for editing using various commands. Basic edits can be made using commands like //set, //replace, and //undo. For Bedrock Edition, users must download the add-on package, enable experimental features, and use semicolon commands for editing. The add-on also includes item shortcuts and management commands for access. The main differences between Java and Bedrock versions include the installation process, permissions, and command prefixes.

Building a True Per-App Android Device Spoofer

Device spoofing in Android applications allows developers to manipulate device information, primarily through altering android.os.Build attributes. Existing spoofer applications often fail to modify native system API calls that retrieve genuine device information. Tweaks is a per-app spoofer integrated into AOSP and LineageOS, which changes device properties by modifying memory-mapped files under /dev/properties. It uses a private mount namespace to bind-mount modified property-context files, ensuring only the targeted application receives spoofed values while the rest of the system remains unaffected. The Tweaks app, which is platform-signed, communicates with the TweaksManagerService to write configurations and manage property overrides. The core functionality is handled by propgen, which generates property context files with spoofed values by identifying and patching properties in place. The TweaksManagerService ensures secure interactions and content-addresses generated property areas to allow sharing among apps with identical overrides. The spawn path in ProcessList.startProcess determines whether to apply spoofing based on conditions evaluated by the TweaksLocalService. Security is maintained through SELinux policies, which restrict access to spoofable properties. However, certain elements, such as /proc/self/mountinfo and /system/build.prop, still reveal authentic device information despite the spoofing capabilities of Tweaks. The source code for Tweaks and related patches is available for public access.

Microsoft Confirms WSUS Sync Issue Causing Update Delays and Timeouts

Microsoft has identified synchronization delays and timeout errors affecting Windows Server Update Services (WSUS), which risks the timely delivery of Windows updates. WSUS is a management tool for distributing Windows updates across networks. Microsoft deprecated WSUS in September 2024 but continues to provide security fixes and updates. The synchronization issue has led to failures and delays in downloading update metadata, particularly impacting Windows 11 version 23H2 and later, Windows 10 version 1607, and Windows Server 2012 and later. This issue began around July 13, 2026, with mitigation efforts starting on July 18, 2026. Microsoft has released a partial fix for newly installed or rebuilt WSUS servers, while existing servers may still face challenges. The company is developing additional fixes and guidance. In previous years, Microsoft dealt with other WSUS-related issues affecting enterprise clients.
