Avast Antivirus is a family of cross-platform internet security applications developed by Avast for Microsoft Windows, macOS, Android, and iOS. Avast offers free and paid products that provide computer security, browser security, antivirus software, firewall, anti-phishing, antispyware, and anti-spam, among other services.[2]

Avast launched a freeware business product, Avast for Business, in February 2015. It includes antivirus protection, web threat scanning, browser protection, and a cloud management console.[3]

As of 2017, Avast is the most popular antivirus vendor on the market,[4] and it had the largest share of the market for antivirus applications.[5]

In January 2020, multiple news sources reported that Avast Antivirus, through a subsidiary, was selling the browsing history of Avast Free product users. Though the company claimed all data was "de-identified", it was reported that the sold data could be linked back to people's real identities, exposing every click and search they had made, but this could not be verified.[6][7][8] In response, Avast announced that it would close the subsidiary over the data privacy backlash.[9]
