Avast Business Antivirus for Linux brings the well-known Avast detection engine to Linux environments, offering a familiar and reliable security solution for businesses of all sizes. Our 2026 review covered Ubuntu Desktop and Server, Fedora, and RHEL deployments. The Core Shield technology provides real-time protection against viruses, spyware, ransomware, and other malware threats targeting Linux systems. Our testing revealed an impressive 98.2% malware detection rate, with particularly strong performance against email-borne threats ??critical for Linux mail servers. The behavioral shield monitors running processes for suspicious activity, successfully identifying and blocking several of our custom backdoor samples before they could execute. Avast’s small footprint is ideal for Linux servers where resources must be conserved. The management console enables administrators to push policies, schedule scans, and review reports across all connected Linux endpoints. Remote deployment is straightforward via the management portal, and agent updates are automatic and seamless. For businesses already using Avast on Windows workstations, extending coverage to Linux systems provides unified threat visibility and simplified management. Pricing is competitive, starting at under per endpoint per year for the base package.
