Best Free Antivirus Software 2026

Over the past decade, free antivirus software has significantly improved, now competing with paid security suites in malware protection. Independent testing from 2026 shows that Avast and AVG have achieved top scores in protection, performance, and usability. Microsoft Defender is a reliable option for Windows users who prefer not to install additional software. The leading free antivirus options in 2026 include Avast Free Antivirus, AVG AntiVirus Free, Microsoft Defender Antivirus, Bitdefender Antivirus Free, Avira Free Security, and Malwarebytes Free. Avast Free Antivirus received perfect scores of 6/6 in protection, performance, and usability from AV-TEST in May and June 2026, totaling 18 out of 18. AVG AntiVirus Free matched these scores and also received an Advanced+ rating from AV-Comparatives. Microsoft Defender scored 6/6 in protection, 5.5/6 in performance, and 6/6 in usability, totaling 17.5 out of 18. Bitdefender Antivirus Free is recognized for its lightweight protection, while Avira Free Security offers additional utilities. Malwarebytes Free is noted for its effectiveness in malware removal. Antivirus software is essential in the current cybersecurity landscape, which includes threats like ransomware and phishing attacks. In 2025, the FTC reported approximately .8 billion in fraud losses, a 25% increase from the previous year. While antivirus software cannot eliminate all forms of online fraud, it plays a crucial role in preventing attacks from escalating to data theft or system compromise. Users should be cautious of counterfeit antivirus software and are advised to download programs from official vendor websites. Free antivirus solutions generally focus on malware detection, while paid options offer additional services. For Windows 11 users, Avast Free Antivirus, AVG AntiVirus Free, and Microsoft Defender are recommended options based on 2026 evaluations.

Google adds Gemini code conversion for PostgreSQL migrations

Google has enhanced its Database Migration Service with AI-assisted code conversion for PostgreSQL migrations from commercial databases. This feature addresses the challenge of converting stored procedures, triggers, and custom functions written in proprietary languages. The new workflow allows users to view original source code alongside suggested PostgreSQL PL/pgSQL output, enabling inline explanations, code editing, and validation before deployment. The service analyzes schema context across the migration project, considering table relationships and data types. It combines rule-based conversion with AI-generated suggestions and includes PostgreSQL syntax validation. The conversion process remains within the customer's Google Cloud project, adhering to security protocols. This feature aims to reduce the time for code conversion from months to days, allowing database specialists to focus on verification and application modifications. Once validated, the converted code can be applied to staging systems for testing before live migration.

Migrating mission-critical payments at Nubank to Amazon Aurora PostgreSQL

Nubank, a digital banking platform with approximately 135 million customers in Brazil, Mexico, and Colombia, faced challenges with its payment infrastructure due to inefficiencies in managing 7.5 TB of self-hosted PostgreSQL databases. Queries took over 13 minutes to execute, and replication lags exceeded four minutes during peak times. To address these issues, Nubank evaluated database solutions based on developer productivity, operational efficiency, performance reliability, and scalability. They selected Amazon Aurora PostgreSQL-Compatible Edition for its compatibility, performance improvements, and automated features. The migration to Aurora was facilitated by AWS Database Migration Service (AWS DMS), which minimized downtime and allowed for efficient transition. Post-migration, query performance improved significantly, with some queries executing up to 1,900 times faster, and overall end-to-end service latency decreased, enhancing customer experience. The migration resulted in a 25 percent cost reduction and ensured compliance with regulatory requirements.

I found a hidden way to limit RAM on Windows 11, and the results were way more surprising than I expected

Windows 11 allows users to limit RAM usage through the System Configuration tool (msconfig) for testing and troubleshooting purposes. Users can specify the maximum memory in megabytes, but there is no simple option to set a fixed amount like "4GB of RAM." Limiting RAM can degrade performance and may cause applications to become sluggish. To limit RAM, users must navigate to the Boot tab in msconfig, check the Maximum memory option, and enter the desired amount. To restore full RAM access, users need to uncheck the Maximum memory option in the same tool. On some modern systems with UEFI firmware and Secure Boot enabled, the Maximum memory setting may not be accessible, and disabling Secure Boot may be necessary to apply the limit. Disabling Secure Boot can reduce security against boot-level malware.

Ookla’s Windows 11 Speedtest mockup looks suspiciously like macOS

Ookla and Microsoft announced a partnership to integrate Speedtest as the network performance testing platform across Bing and Windows, allowing Windows 11 users to check their internet speed from the taskbar. This feature was initially available to Windows Insiders in February 2023. A humorous remark by Rafael Rivera, a Windows Dev MVP, suggested that Ookla leaked a glimpse of the Windows vNext UI, which appeared to include elements from macOS. The incident has sparked discussions about design trends and user interfaces in the tech community.

What is the best PC antivirus for 2026: Acronis True Image vs. competitors

In 2026, traditional antivirus solutions are becoming outdated due to the rise of sophisticated cyber threats, including AI-driven ransomware and advanced phishing schemes. The FBI Internet Crime Report states that cybercrime losses exceeded .5 billion in 2023, with projections by Cybersecurity Ventures estimating costs could reach trillion annually by 2025. Research from IBM shows that organizations without a tested recovery plan face higher costs and longer downtimes. Built-in protections like Windows Defender and MacOS XProtect offer basic security but may leave gaps, necessitating comprehensive third-party antivirus solutions. Acronis True Image is highlighted for its unique combination of real-time malware protection and full system backup capabilities, enabling users to recover quickly from incidents. Other leading antivirus solutions, such as Norton 360, Bitdefender, McAfee, and Kaspersky, excel in threat prevention but lack integrated recovery options. Acronis emphasizes the importance of both security and continuity, preparing users for both cyber incidents and everyday failures.

Windows 11’s Gaming Gains Overshadowed by Stability Crisis: Performance Tests Reveal a Troubled Transition

Microsoft's Windows 11 version 24H2 shows performance improvements in gaming, with frame rate enhancements ranging from 2% to 8% across various titles, particularly benefiting newer DirectX 12 games. However, users report significant stability issues, including Blue Screen of Death (BSOD) errors, crashes during gameplay, and compatibility problems with certain hardware and software. These issues affect a wide range of systems, suggesting systemic challenges rather than isolated incidents. The operating system's hardware compatibility requirements, such as TPM 2.0 support, have also limited upgrade eligibility for many users. Microsoft has acknowledged specific issues related to Intel and AMD processors, antivirus software conflicts, and outdated drivers. Despite ongoing patch deployments, user frustration persists due to the slow pace of fixes. The stability concerns have led some businesses to delay Windows 11 24H2 deployments, prioritizing reliability over performance gains. The driver ecosystem's lag in updates from hardware manufacturers has further complicated stability. The gaming community remains divided, with many users opting to stay on Windows 10 due to these stability risks.
