In 2026, ESET introduced features like a Website Security Inspector and a Microphone Monitor, while IPVanish's antivirus includes real-time anti-ransomware protection and machine-learning threat detection. Security.org's 2025 report indicated that 84% of users made no changes to their antivirus software over the past year, with many only reconsidering when faced with price increases or product discontinuations. The choice between paid and free antivirus solutions is significant, with 54% of third-party users paying for their software. ESET's Ultimate tier is the only one that includes ransomware backup features. Before switching antivirus products, users should ensure they are running compatible operating systems, have administrator access, document current and new antivirus version numbers, and have a stable internet connection. A PowerShell command can check the current antivirus status. Steps for migration include auditing current antivirus features, choosing a suitable replacement, exporting license keys, and using official removal tools to uninstall the old software. After installation, users should verify real-time protection is active and rebuild exclusions and scan schedules. Common pitfalls during migration include failing to uninstall the old antivirus completely, forgetting to disable tamper protection, and losing exclusion lists. For mobile devices, permissions from the old antivirus must be cleared to avoid conflicts. Advanced users managing multiple devices may benefit from staggering migrations and checking for known vulnerabilities in the antivirus products. A PowerShell script can be created to log the antivirus state before and after migration.

Windows 11’s last Secure Boot deadline hits Monday, Microsoft reveals what happens to your PC

Microsoft Windows Production PCA 2011, the certificate for signing the Windows boot loader, will expire on October 19, 2026. This follows the earlier expiration of two other 2011 certificates in June 2026. PCs without the new certificates will still boot and receive standard updates but will miss out on new security enhancements for the early boot process. The new certificates from 2023 are replacing the 2011 certificates. The KEK certificate, essential for authorizing updates to signature databases, and the Microsoft UEFI CA 2011, which signs third-party boot loaders, will also be replaced by new certificates. Users can check their Secure Boot status through the System Information tool or Windows Security. Microsoft is gradually rolling out the new Secure Boot certificates through Windows Update, and users are advised not to disable Secure Boot to avoid complications. Dell will not issue BIOS updates for platforms that reached their end of service life before January 1, 2026. The transition to Secure Boot has faced challenges for older PCs, and developers are advised against pinning Secure Boot certificates in their applications. Multiple restarts may be required for full integration of the new certificates.

Android Malware Caught by Teaching AI to Read Apps as Pictures

A research team from Turkey, led by Erdal Başaran and Ömer Okucu of Ağrı İbrahim Çeçen University, along with Yusuf Alaca from Hitit University, has developed an innovative detection framework for Android malware that utilizes a visual approach. This framework transforms key features of Android applications into images, allowing a Vision Transformer to differentiate between benign software and malware. The researchers created two types of images from static and dynamic analysis features: a conventional 2D grayscale image and a QR code image. Separate Vision Transformer models were trained on each image type, and spatial pooling features were extracted from deeper layers to create a comprehensive representation of application behavior. To refine the fused feature vector, Recursive Feature Elimination (RFE) was employed, enhancing classification clarity and reducing computational load. The final classification utilized a majority-voting ensemble strategy, achieving a detection accuracy of 98.72 percent, surpassing standalone models. The study demonstrates that the multimodal system outperforms individual grayscale or QR code pathways. The dataset used is publicly available, promoting reproducibility. The framework's reliance on static and dynamic analysis features allows it to adapt to new threats, and the novel QR code representation offers distinctive visual signatures of malicious behavior. However, challenges remain regarding feature extraction quality and computational demands.

VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.
