Bitdefender Antivirus Free has been engineered to enable you to enjoy your computer to the max, without having to worry about viruses and other e-threats. Call it "artificial intelligence" because it will always find the best way for your system to stay clear of dangers without requiring special configuring.
  • Free antivirus protection effectively stops even the fastest-evolving attacks.
  • It runs silently in the background and stays out of the user's way.
  • The antivirus software is impossibly light on the CPU, ensuring it won't consume the system's resources.
  • It includes live customer support, distinguishing it from other free antivirus software options.
And, more importantly, without slowing down your system. Bitdefender Free Edition shares some of the revolutionary technologies that allowed the main product line to outpass major competitors such as AVG, Avast, or Avira.

Bitdefender Free Edition is a lightweight antivirus program designed to safeguard your computer against various forms of malware, including viruses, spyware, Trojans, ransomware, and more. Developed by Bitdefender, a reputable name in the cybersecurity industry, this free version provides essential security features to protect your system and data from online threats.

Bitdefender Antivirus Free Edition uses a combination of Cloud scanning and behavioral analysis to detect new or unknown threats that other antiviruses miss. It uses proprietary technology, as well as other technologies integrated to provide maximum strength against e-threats.

Exclusive, top-of-the-heap defense:

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 by malware. Intrusion Detection is automatically alerted when such apps behave in a suspect manner and block them when they go over the limit.

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, Antivirus Free version scans all the links you access from your web browser and blocks them when they prove to be unsafe.

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

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 on virus detection efforts in risky areas.

On-demand Scanning
You can perform manual scans of specific files, folders, or your entire system to check for any potential malware.

Detected threats are isolated and placed in quarantine to prevent them from causing harm to your computer.

The software helps protect your personal information by blocking suspicious websites that may attempt to steal your sensitive data.

Automatic Updates
It automatically updates its virus definitions, ensuring that you are protected against the latest threats.
