Free antivirus solutions have improved significantly, providing users with protection that was once exclusive to paid software. Major players in the market include Avast, Bitdefender, AVG, and Malwarebytes, each offering distinct features and limitations. While effective against common threats like viruses and malware, these free tools often lack advanced privacy tools and comprehensive security coverage. Avast One Basic offers real-time scanning and basic tools like a VPN and system cleanup, while AVG AntiVirus Free provides a streamlined user experience with a focus on simplicity. Avira Free Security includes additional features such as a basic VPN and privacy management tools, making it a more comprehensive free option. McAfee Free serves as an introduction to its broader ecosystem but lacks depth in protection. Free antivirus tools remain popular due to improved everyday protection, ease of use, and cost-effectiveness, especially for mobile users. They utilize cloud intelligence for better performance and can handle basic security needs. However, they may not suffice for users with high-risk profiles or those needing advanced privacy features. Key criteria for free antivirus solutions include core protection through real-time monitoring, seamless performance, user-friendly interfaces, and additional valuable tools. Limitations include basic protection against emerging threats, intrusive upgrade prompts, slower updates to threat databases, limited support options, and potential privacy trade-offs. Alternatives to free antivirus software include Bitdefender, Surfshark One, Norton 360, Avast Premium Security, and Avira Prime, which offer more robust protection and features.

Google is revising its approach to Android sideloading by allowing users to install applications from unverified developers while implementing a new 24-hour process to enhance security. Users must activate developer mode, confirm their decision, restart their devices, and re-authenticate before installation. A one-time 24-hour waiting period is also introduced to prevent scams. This change addresses concerns from developers and advocacy groups about the impact of stringent verification policies on smaller developers. Google is also offering limited-distribution accounts for students and hobbyists to share apps without full verification. The updated process includes additional security measures to disrupt scams, while users are encouraged to use dedicated security solutions for better protection against mobile threats.

The ransomware group LeakNet has evolved its tactics, increasing its average targets from three per month and shifting from purchasing stolen network access to launching its own campaigns. They now use deceptive error screens and a new tool that executes malicious code in a computer's memory. Their strategy includes ClickFix lures, which compromise legitimate websites to display fake security checks, tricking users into executing malicious commands. This method broadens their victim reach and reduces costs. The Deno loader, part of this strategy, collects machine information and retrieves additional malicious code without leaving standard files, making detection difficult. After infiltrating a network, LeakNet checks for active user credentials and uses PsExec for lateral movement, employing Amazon S3 buckets for payload staging and data exfiltration. Defenders are advised to monitor for suspicious behavior rather than just known malicious files, focusing on unusual web commands and unexpected cloud storage connections.

Cybersecurity researchers have identified a new family of Android malware called Perseus, designed for device takeovers and financial fraud. It utilizes Accessibility-based remote sessions for real-time monitoring and interaction with infected devices, particularly targeting Turkey and Italy. Perseus monitors user notes to extract personal or financial information and is distributed through dropper applications via phishing websites. It expands on the codebase of previous malware like Phoenix and employs disguises as IPTV services to reduce user suspicion. Once operational, it performs overlay attacks and captures keystrokes to steal credentials from financial applications. The malware allows operators to issue commands through a command-and-control panel, enabling various malicious actions, including capturing note content and initiating remote visual streams. Perseus also conducts environment checks to evade detection and ensure it operates on legitimate devices.

The digital landscape is transforming due to the professionalization of cybercrime, which is now a significant part of organized crime, second only to drug trafficking. Malware includes various types such as viruses, browser hijackers, password stealers, Trojans, botnet malware, and ransomware. Traditional antivirus solutions rely on signature-based detection, heuristic analysis, and behavior monitoring, but these methods can lead to false positives and negatives. The evolution of cybersecurity has seen the rise of "Ransomware-as-a-Service" (RaaS) and the use of polymorphic malware that changes its signature, making traditional defenses ineffective. Hackers are also using AI and machine learning to evade behavioral monitoring. New defense strategies include Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR), which focus on monitoring for breaches rather than preventing them. Leading vendors in this space include CrowdStrike, SentinelOne, Microsoft, and Palo Alto Networks. The zero trust security framework treats all access attempts as potentially hostile and emphasizes the integration of various security technologies. Emerging startups like FinalAV Security are developing zero trust solutions for consumers and small businesses, focusing on prevention rather than detection.

Postgres extensions, specifically pg_lake, pg_partman, and pg_incremental, provide a vendor-agnostic, open-source solution for managing high-performance time series data. PostgreSQL serves as the foundation, while pg_partman automates time partition management, pg_lake connects Postgres with data lakes for offloading cold data, and pg_incremental processes append-only data in batches. These extensions are maintained by the Postgres team at Snowflake. An example system for monitoring temperature readings uses local storage for recent data and transitions cold data to an Apache Iceberg table on S3. The process includes creating a partitioned table in Postgres, establishing an Iceberg table, using pg_incremental for data appending, eliminating old partitions with pg_partman, and querying from both local and cold tables to optimize storage and costs. A time-partitioned table enhances performance by allowing efficient deletion of outdated data, speeding up queries, and reducing fragmentation.

Surfshark has launched the Surfshark One bundle, which includes a VPN, antivirus protection, data breach monitoring, alternative ID features, and private search capabilities. The 24-month plan offers significant savings, costing approximately .49 per month, while the 12-month plan costs .99 per month. The antivirus tool scans for malware and provides real-time monitoring. It also alerts users if their personal information appears in data breach databases, allowing them to take action. The private search tool ensures searches are not tracked or linked to personal profiles. All plans come with a 30-day money-back guarantee.

Widespread mobile Internet outages have affected Moscow for over a week, disrupting daily life for its 12 million residents and impacting services like online payments and navigation. Since March 7, offline solutions such as pagers and paper maps have seen increased demand. The Kremlin attributes the disruptions to heightened security measures amid ongoing tensions with Ukraine. Critics argue that the government uses security as a pretext to control citizens' lives. Mobile Internet disruptions have been present in Russia since June 2025 but have only recently intensified in Moscow. Freelancers report negative impacts on their work due to the outages. The Russian government has been managing Internet usage by targeting Western tech companies and promoting domestic alternatives. Access issues have also affected popular apps like Telegram. A law signed by Putin on February 20 allows the Federal Security Service (FSB) to request service suspensions from telecommunications operators, exempting them from liability for compliance. The government has a history of censoring online content and tightening control over civil liberties since Putin's return to power in 2012, with measures intensifying since the invasion of Ukraine began in 2022.
