Federal Circuit Finds that Antivirus Software is Abstract and Remands for Alice, Step Two

Columbia University faced a setback in its patent dispute with Gen Digital Inc. regarding U.S. Patents 8,074,115 and 8,601,322, which relate to an innovative virus detection method developed in the early 2000s. The method involved evaluating the behavior of suspicious code using an emulator and a model of expected behavior derived from data across interconnected computers. Columbia initiated legal proceedings in 2013, and after various developments, a jury awarded Columbia over million in royalties for willful infringement in 2022. However, the Federal Circuit ruled that the patent claims were not sufficiently specific and remanded the case for further examination of whether the claims could constitute an inventive concept. The ruling emphasized that patent eligibility is determined by the precise language of the claims.

Best Antivirus for Windows 11: Fast, Lightweight & Secure

Windows 11 users face various cyber threats, making antivirus software essential. Many users mistakenly believe they are adequately protected by Windows Defender, which, while improved, may not be sufficient against modern threats. Effective antivirus solutions provide real-time protection, monitor behavior, and block phishing attempts, adapting to evolving threats. Key features to consider include low system impact, unobtrusiveness, and comprehensive protection across multiple devices. Popular antivirus options for 2026 include Bitdefender, Surfshark One, Norton, and Avast. Free antivirus tools offer basic protection but lack advanced defenses against phishing and ransomware. Paid solutions enhance security with features like real-time monitoring and additional privacy tools. Proper installation and configuration are crucial for optimal performance and protection. Users should choose antivirus software based on their individual habits and needs, ensuring it integrates seamlessly into their daily routines.

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In 2026, traditional antivirus solutions are becoming outdated due to the rise of sophisticated cyber threats, including AI-driven ransomware and advanced phishing schemes.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.
