Avast Ultimate 2026 – 1 year / 1 device

Avast Ultimate 2026 is the latest generation of Avast's all-in-one pack, for 1 device for 1 year. It brings together the Premium Security antivirus suite, the SecureLine VPN, the Cleanup Premium optimiser and the AntiTrack Premium anti-tracking tool. The appeal of the pack is that it covers four distinct needs — security, connection privacy, performance and online privacy — with a single subscription and a single dashboard.

What the protection includes

• Continuous antivirus protection — files, downloads and removable media are scanned before they run.
• Anti-ransomware shield — your personal folders can only be modified by approved applications.
• Firewall and anti-phishing — network filtering and blocking of pages that imitate banks and shops.
• SecureLine VPN — encrypted connection and masked IP address, particularly on public Wi-Fi.
• Cleanup Premium — recovery of disk space, sleep mode for background applications and scheduled maintenance.
• AntiTrack Premium — masking of the browser fingerprint and blocking of advertising trackers.

Compatibility

Up-to-date Windows 11 and Windows 10 for all modules; the antivirus and the VPN also exist on macOS, Android and iOS. The licence covers a single device, freely chosen. An Internet connection is essential.

Activation

Your activation key arrives by email within 24 hours at most after the order is confirmed. Attach the code to your Avast account, then install the modules on the device of your choice. The 12-month period runs from activation.
