Avast Ultimate 2025 – 1 year / 1 PC

Avast Ultimate 2025 brings together Avast's four major programs in a single licence valid for 1 year on 1 PC: the Premium Security antivirus suite, the SecureLine VPN, the Cleanup Premium optimiser and the AntiTrack Premium anti-tracking tool. It is a recent edition, which brings enhanced detection of online scams and fraudulent messages in addition to the classic antivirus protection.

What the protection includes

• Real-time antivirus and behavioural detection — blocks viruses, Trojans and ransomware, including threats with no known signature.
• Firewall and payment protection — filters connections and verifies the authenticity of banking sites.
• Scam detection — flags booby-trapped links, fake delivery emails and fake shops.
• SecureLine VPN — encrypts your traffic and masks your IP address, with no data limit.
• Cleanup Premium — removes unnecessary files, puts background applications to sleep and shortens Windows start-up.
• AntiTrack Premium — prevents advertising networks from rebuilding your browsing profile.

Compatibility

Up-to-date Windows 11 and Windows 10, 32 and 64 bit, for all modules. 2 GB of RAM and 2 GB of disk space recommended. An Internet connection is required for activation, the VPN and updates.

Activation

The activation key is sent by email within 24 hours at most. Sign in to your Avast account, enter the code to attach the Ultimate subscription, then install each module: the licence is recognised automatically. The 12-month period starts at activation.
