"What makes Bitdefender better than other free antiviruses?"

Bitdefender Antivirus Free Edition uses a combination of Cloud scanning and behavioural analysis to detect new or unknown threats that other antiviruses miss.

Exclusive, top-of-the-heap defense

Bitdefender uses proprietary technology, as well as other technologies integrated to provide maximum strength against e-threats.

  • Real-time Shield

    The real time shield is designed to protect your entire system from infected files coming from the outside, before they have a chance to spread inside your PC.

  • Active Virus Control

    Proactive technology that quickly and accurately detects potential threats, even in cases of new viruses for which there is no default protection released yet.

  • Intrusion Detection System

    Ensures that applications trying to access the Internet or the network are not masked malware. Intrusion Detection is automatically alerted when such apps behave in a suspect manner, and blocks them when they go over the limit.

  • B-Have

    Proactively detects unknown threats that other products miss, by analyzing how apps behave in a safe environment. If no malicious actions are detected, B-Have starts the program normally. Otherwise, it will automatically quarantine or delete it.

  • HTTP Scanning

    Protects you from scams such as credit card phishing attempts, Bitdefender Antivirus Free Edition scans all the links you access from your browser and blocks them when they prove to be unsafe.

  • Anti-rootkit

    Rootkits are a type of stealth software, often malicious, that can help hackers get control of your computer. Bitdefender Antivirus Free Edition uses special technology that detects and blocks such malicious software.


Light. Automatic.

Bitdefender Antivirus Free Edition uses an intelligent mechanism that can automatically take the optimum decisions to provide ironclad security without slowing down your computer.

  • Early Boot Scanning

    This technology scans the system at boot time, as soon as all critical services are loaded. Early boot scanning ensures virus detection at system startup, while also improving boot time.

  • Auto Scan

    A huge time and resource saver, Auto Scan is a Bitdefender proprietary technology that focuses virus detection efforts on risky areas.
