About Avast One

Avast One represents a significant redesign of Avast's product line, consolidating their antivirus, VPN, and cleanup tools into a single unified platform. The free tier is remarkably generous: you get real-time malware protection, a VPN with 5GB weekly data, a basic firewall, and system cleanup — all at no cost. In malware detection tests, Avast achieved a 98.2% detection rate with moderate system impact. The paid plans unlock unlimited VPN data and advanced features like sensitive data monitoring.
