Avast Free Antivirus for Windows is a free malware protection software designed for American home users, operating under Gen Digital, which also includes Norton. It provides essential security features such as real-time scanning, on-demand scans, and regular updates, but has limitations compared to paid versions, including the absence of features like VPN and advanced ransomware protection. The software is intended for home PC use and is available for download on Windows PCs. While it serves as a basic defense against common malware threats, it is not suitable for small businesses needing comprehensive security solutions. Users are advised to maintain safe browsing habits even with the antivirus installed.

A security researcher has developed a proof-of-concept tool called GhostLock, which exploits a vulnerability in the Windows file API, specifically the 'CreateFileW' function. By manipulating the 'dwShareMode' parameter to grant exclusive access to files, GhostLock can prevent other users or applications from opening those files, resulting in a 'STATUSSHARINGVIOLATION' error. The tool automates the process of opening multiple files on SMB shares, causing access disruptions without requiring elevated privileges. This technique is intended as a disruption attack rather than a destructive one, similar to ransomware, and can serve as a diversion during intrusions. Detection of this attack relies on monitoring the open-file count with ShareAccess set to 0 at the file server layer. Dvash has provided resources for IT teams to enhance detection capabilities against this threat.

The cost of AVG Internet Security includes a single-device plan starting at a specified amount for the first year, which then increases to a higher annual fee, and a multi-device plan for up to ten devices that starts at a different amount for the first year and rises to a specified annual fee thereafter.

On April 3, 2026, Anthropic expanded Claude’s desktop control feature to Windows for Pro and Max subscribers, allowing users to operate applications, navigate web pages, and manage files on their PCs without prior configuration. The feature is in research preview and includes a Dispatch companion for task assignment from mobile devices. Claude uses a structured tool hierarchy for task execution, prioritizing connectors like Slack and Google Calendar, and engages in direct desktop control only when necessary. Users must opt in to activate the feature, which integrates with existing software without requiring API keys. The technology is partly derived from Anthropic’s acquisition of Vercept AI, which specializes in AI-driven computer control. Security concerns have arisen due to vulnerabilities demonstrated shortly after the launch, prompting Anthropic to implement safeguards while acknowledging the feature's potential errors. Users can stop Claude's operations, but the company admits it cannot disable the technology remotely once tasks have started. Competitors like Microsoft and Google are also exploring similar desktop-level AI automation capabilities.

Russian military personnel have been advised to stop using the messaging application Max due to security concerns, as reported by Mediazona. This recommendation follows intensified restrictions on Telegram, which began in the summer of 2025. The Federal Security Service (FSB) has warned that Ukrainian forces can intercept Telegram communications, prompting worries about the safety of sensitive information. Access to Telegram has been increasingly limited, with plans for further restrictions on media file access reported by RBC. Pro-war advocates, including Sergey Mironov, have criticized these limitations and defended Telegram as a reliable communication tool. Despite the Kremlin's claims that troops do not rely on Telegram, the Russian Defense Ministry asserts that they use standard communications equipment and a domestically developed messenger. On February 18, Russian Digital Development Minister Maksut Shadaev stated that Telegram would not be blocked for frontline use for now.
