Avast One Pricing & Plans

For core malware detection, Avast One Free and paid plans use the same antivirus engine, so there is no difference in malware-stopping capability. The substantive security difference in paid plans lies in additional protection layers: unlimited VPN (Free is capped at a limited data allowance), advanced ransomware shields, real-time email and download protection enhancements, and dark web monitoring that actively scans for your personal data in breach databases. Avast One Free provides strong baseline antivirus, while paid plans layer on privacy, identity, and comprehensive web threat coverage that collectively reduce your overall attack surface.
