About Bitdefender Antivirus Free
Bitdefender Antivirus Free is a free security product from the Romanian company Bitdefender. It gives Windows PCs real-time protection against viruses and other malware with a simple interface that needs little setup, and the company is well regarded in independent lab tests.
The free edition keeps its feature set small. Its main strength is the detection engine shared with Bitdefender's paid products, and the paid suites add a firewall, VPN, parental controls and extras. The provided store data actually describes Bitdefender Mobile Security, a separate app for Android and iOS that offers malware scanning, web protection, an account privacy tool and, in a recent update, a Scam Radar alert. Those apps are free to download with in-app purchases for the paid features.
The free Windows antivirus suits people who want an unobtrusive extra layer and who do not need advanced controls. Because the free edition has fewer features than the paid suites, you may see prompts to upgrade. Check the official site for the current Windows availability and pricing of paid plans.
Suitable as a light antivirus for Windows. Make sure you install the Windows product and not the mobile app of the same brand.
