Avast Premium Security 2025 – 1 year / 1 PC

Avast Premium Security 2025 is the recent version of Avast's complete antivirus suite, for 1 PC for 1 year. Beyond the classic antivirus, this edition reinforces the fight against online scams: detection of fraudulent messages, fake shopping sites and pages that imitate a banking service. Added to this are the firewall, the anti-ransomware shield, webcam protection and the isolated environment for opening a suspicious file.

What the protection includes

• Real-time antivirus — permanent scanning of files, downloads and removable media.
• Behavioural and cloud analysis — previously unseen threats are identified by their behaviour, without waiting for a signature.
• Scam protection — flags fraudulent links received by email or message and fake online shops.
• Firewall — monitors incoming and outgoing connections, application by application.
• Anti-ransomware shield — prevents the encryption of your personal folders by an unauthorised program.
• Webcam and sensitive data — controls camera access and detects exposed personal documents.
• Sandbox and file shredder — isolated execution of suspicious executables and permanent deletion of confidential documents.
