Avira Free Antivirus vs Bitdefender Antivirus Plus

Avira Free Antivirus is a freemium internet-security product for Windows, macOS, Android, and iOS. Its Free Antivirus plan costs nothing and includes 500 MB of VPN data per month. The product combines real-time malware monitoring with ransomware protection, a password manager, privacy settings optimization, browser protection, Safe Shopping, PC tune-up tools, and Software Updater. Avira describes coverage for ransomware, spyware, adware, phishing, and zero-day attacks. Detected files can be deleted or quarantined. Browser Safety can block harmful ads and pages and prevent online tracking. The free version uses the same scan engine and cloud-based detection system as Avira Antivirus Pro; the paid version adds signature-based and heuristic analysis and advanced web protection. The free plan is for private, non-commercial use. Free users can seek help from Avira’s worldwide community, while support requests require an Avira license. Avira states it does not sell user data or share it with government, Big Tech, or advertising networks.

Bitdefender Antivirus Plus Multiplatform protects Windows, macOS, iOS, and Android devices against malware, ransomware, scams, and other online threats. Real-time detection covers viruses, ransomware, zero-day exploits, rootkits, and spyware. Web protection blocks phishing and fake-shop sites, and layered ransomware protection safeguards documents, pictures, videos, and music from encryption. On Windows PCs, Vulnerability Assessment checks for outdated or vulnerable software, missing Windows security patches, and potentially unsafe settings.

The included basic VPN allows 200 MB of traffic per day per device; unlimited traffic requires adding Premium VPN.
