Avast Security

Overview

Avast Security is built on the Avast brand (founded 1988, Prague, Czech Republic), one of the world's largest and most recognized free antivirus brands with over 435 million active users. Avast offers a complete product matrix from free antivirus to the all-in-one Avast One security solution, covering virus protection, network security, privacy protection, and device performance optimization.

Avast acquired AVG Technologies in 2016, creating a dual-brand strategy. Its product line includes Avast Free Antivirus, Avast Premium Security, Avast One, Avast SecureLine VPN, and Avast Cleanup. In 2021, Avast merged with NortonLifeLock (now Gen Digital) to form one of the world's largest consumer security software companies.
