Bitdefender Total Security 2025 covers 5 devices for 1 year and is the most complete edition of the current range. What sets it apart from Internet Security: it steps outside the Windows framework to also protect macOS, Android and iOS with the same licence and adds system optimisation tools. The EU label corresponds to the key's validity zone, intended for activation from a European country — which covers Switzerland.
What the protection includes
- Multi-platform antivirus — real-time protection across all four systems, managed from a single account.
- Advanced Threat Defense — behavioural detection of threats without a known signature.
- Multi-layer anti-ransomware protection — blocking of unauthorised encryption and restoration of affected files.
- Safepay — an isolated browser for payments and online banking.
- Firewall, webcam and microphone — network filtering and access control for recording devices.
- Anti-tracking and VPN — blocking of advertising trackers and a built-in VPN, with a limited daily volume in the base version.
- System optimisation — cleaning up junk files and speeding up startup.
Compatibility
Windows 11, 10, 8.1 and 7 (SP1), macOS, Android and iOS. Features vary by platform: the firewall and Safepay are specific to Windows, while the mobile apps focus on app scanning, web protection and anti-theft.
Activation
The activation key is sent to you by email within 24 hours maximum. Sign in to Bitdefender Central, add the code in My Subscriptions, then install the protection device by device. The 12 months run from activation.
