Bitdefender Antivirus Plus 2025 is the Romanian publisher's entry-level Windows offering, for 1 PC for 1 year. The distinction between the three Bitdefender tiers is simple: Antivirus Plus focuses on Windows protection against malware, Internet Security adds the firewall, parental controls and webcam protection, while Total Security extends coverage to macOS, Android and iOS. If you have only a single PC to protect and no multi-platform need, this edition is the most coherent.
What the protection includes
- Real-time antivirus — a detection engine regularly ranked among the best performers in independent tests.
- Advanced Threat Defense — behavioural analysis that spots an unknown threat by its actions rather than its signature.
- Multi-layer ransomware protection — monitoring of sensitive folders and blocking of encryption attempts.
- Safepay — an isolated, hardened browser for banking operations and online purchases.
- Anti-phishing and anti-fraud — blocking of pages that imitate a legitimate site to capture your credentials.
- Autopilot mode — security recommendations and decisions taken automatically, without constant prompting.
Compatibility
Windows 11, 10, 8.1 and 7 (SP1). Allow for 2 GB of RAM and 2.5 GB of free disk space. Bitdefender is known for its low impact on performance, with most of the scanning offloaded to its servers.
