Avast Premium Security – 1 year / 1 PC

Avast Premium Security is Avast's complete antivirus suite, to be distinguished from the free version: it adds a firewall, online payment protection, the anti-ransomware shield, webcam control and the sandbox. This licence covers 1 PC for 1 year. It is the simplest option for securing a single home or business computer without multiplying subscriptions.

What the protection includes

• Permanent antivirus shield — every file opened, downloaded or copied from a USB stick is checked before it runs.
• Firewall — filters network traffic and blocks intrusion attempts, with automatic tightening on public Wi-Fi.
• Anti-ransomware — only the programs you approve can modify your documents and photos.
• Real Site and anti-phishing — protects you from pages that imitate your bank or a well-known shop.
• Webcam protection — every camera access request must be approved.
• Sandbox — opens a suspicious executable in a space isolated from the system.
• Data shredder — deletes a file in an unrecoverable way.
• Wi-Fi Inspector — detects weaknesses in your router and unknown devices on the network.

Compatibility

Windows 11, 10, 8.1 and 7 (SP1), 32 and 64 bit. 1 GB of RAM and 2 GB of free disk space recommended. An Internet connection is required for activation and signature updates.
