Bitdefender Antivirus Free

Bitdefender Antivirus Free is a free antivirus software especially designed to protect your Windows PC. Quick to install and light on computer resources, it is good for gaming, image and video editing, and resource-intensive applications. Once you have installed Bitdefender Antivirus Free, your device is protected against all kinds of threats (such as malware, spyware, ransomware, exploits, botnets and trojans) and internet threats (such as hackers, phishing and spam). The app uses the Photon technology to enhance the speed and performance of the threat scanning process. It works by learning the usage patterns of your system apps to know what and when to scan, thus minimizing the impact on system performance.

Many free antivirus solutions are as intrusive and resource-heavy as the viruses they’re supposed to stop. Only Bitdefender Antivirus Free is designed from the ground up to keep you safe without disrupting your workflow and focus.

Free antivirus protection that stops even the fastest-evolving attacks
Runs silently in the background and stays out of your way
Impossibly light on CPU (will not slow down your computer)
Live customer support included (unlike other free antivirus software)
