Free antivirus software provides essential protection against viruses, malware, and online threats without cost. Key features often include real-time scanning, automated updates, and basic security measures. Notable free antivirus programs for 2025 include: - Bitdefender Antivirus Free Edition: Offers real-time protection, on-demand scanning, and anti-phishing features with low system impact. - Avira Free Security: Includes real-time protection, web protection, a VPN, a password manager, and a system optimizer. - Sophos Home Free: A cloud-managed solution that uses AI for threat detection and includes parental controls. - AVG AntiVirus Free: Known for reliable protection against malware and includes a ransomware decryption tool. - Microsoft Defender: Built into Windows, it provides decent protection and receives regular updates. Choosing the right antivirus depends on individual needs; options vary in features and performance impact. Free antivirus programs typically lack advanced features found in paid versions, such as comprehensive malware detection, firewall protection, and priority customer support. Independent labs test antivirus software for effectiveness, focusing on detection rates, false positives, and performance impact. Some free antivirus tools offer additional features like password managers and limited VPN access, but many advanced functions require payment. Overall, while free antivirus solutions may not be as comprehensive as paid options, they still provide solid protection for everyday users.

AMD launched the Zen 5-powered Ryzen 9000 processors, facing initial challenges including delayed sample deliveries and disappointing early reviews that reported minimal performance improvements in gaming. However, retesting showed that the Ryzen 5 9600X and Ryzen 7 9700X outperformed their predecessors by approximately 12%. The Ryzen 7 9700X achieved a 9.3% gain and the Ryzen 5 9600X reached a 10% increase under stock configurations, while gains diminished to 6.6% and 7.8% with AMD’s Expo memory overclocking. Built-in benchmarks indicated higher generational performance compared to custom game scenes, with built-in benchmarks showing an 11.00% gain for the Ryzen 7 9700X versus an 8.50% increase in custom scenes. The Windows 11 23H2 update positively impacted AMD’s performance, while Intel's performance gains from the same update were minimal, with the Core i9-14900K and Core i5-14600K showing no substantial improvements.

AMD's launch of the Ryzen 9000 desktop processors revealed performance discrepancies between the company's marketing claims and independent reviewer results. AMD identified several factors contributing to these differences, including variations in Windows operating modes, VBS security settings, Intel system configurations, and game selections for benchmarking. The company used an automated testing framework in Super Admin mode, which allowed for optimizations not present in the standard user mode used by reviewers. This led to inflated performance numbers that did not account for the differences between the two modes. AMD's David McAfee stated that the gap in performance between Super Admin and user modes had widened over time, which they had not anticipated. Additionally, the selection of games and specific scenes for benchmarking significantly impacted performance results. McAfee clarified that AMD did not blame reviewers for the discrepancies, attributing them instead to its own testing decisions. AMD is committed to refining its testing methodologies for better alignment with real-world user experiences.
