Avast Premium Security 2026 - 12 months / 1 device

Avast Premium Security: antivirus with firewall and ransomware protection

Avast Premium Security is Avast's paid security suite. It adds a firewall, ransomware protection, a sandbox for suspicious files and features against fraud attempts by email and via fake websites to real-time virus protection. According to Avast, the version for 1 device with a term of 12 months is intended for one Windows PC or one Mac.

Protection against malware

On Windows, real-time protection continuously checks files and programs for viruses, spyware and other malware. Behavior Shield reports when an installed application behaves suspiciously, and CyberCapture examines downloaded files. A dedicated Ransomware Shield is aimed at malicious programs that encrypt personal files. Suspicious files can be opened in the Sandbox, an isolated environment from which they cannot modify the installed system.

Firewall, privacy and fraud protection

The Firewall blocks unauthorised access to the PC, and Remote Access Shield is aimed at attempts to take over the computer remotely. Webcam Shield prevents programs that have not been approved from accessing the camera, and Passwords Protection protects the passwords stored in the browser. Fraud attempts are countered by Email Guardian, which flags suspicious messages, the detection of fake websites and an AI-powered assistant that helps you assess scams. With Data Shredder, files can be deleted permanently, for example before a computer is passed on.

Features on the Mac

On the Mac, Premium Security includes real-time protection, enhanced ransomware protection, email protection, detection of fake websites and warnings about vulnerabilities and unknown devices on the Wi-Fi network.

Avast Ultimate includes Premium Security plus the Avast Premium VPN (formerly SecureLine VPN), the Cleanup Premium maintenance program and AntiTrack against tracking in the browser. If you would also like to use these applications, choose Avast Ultimate 2026 (12 months, 1 device).
