Avast Antivirus Overview

Avast is a widely used security product for Windows with a popular free antivirus tier and paid plans that add more protection. The free edition covers core real-time malware protection, while paid tiers add a firewall, ransomware shield, a VPN, web and email protection, and PC-optimization tools. Following Avast's merger with AVG (both now under Gen Digital), the two products share the same underlying detection engine. Avast has a large user base that feeds its cloud threat intelligence. It uses a freemium model. It also includes a Wi-Fi inspector that scans your home network for weak points, a sandbox for running suspicious files safely, browser-cleanup tools, and a behavior shield that watches for programs acting maliciously. The official Avast Antivirus download is linked on this page, straight from Avast Software s.r.o..
