Avast Antivirus is a family of cross-platform internet security applications developed by Avast for Microsoft Windows, macOS, Android and iOS. The Avast Antivirus products include freeware and paid versions 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 is a cross-platform solution that 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 a February 2018, test of various antimalware products by AV-TEST, Avast Free Antivirus has earned 6 out of 6 points in "Protection" category, detecting 100% of malware samples used in this test and earning an "AV-TEST Certified" seal.[6] Avast's Mobile Security & Antivirus app detected 100% of malware samples in January 2018 test of Android malware by AV-Comparatives.[7]

In January of 2020, multiple news sources reported that Avast Antivirus, through a subsidiary, was selling the browsing history of Avast 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.[8][9][10] In response, Avast announced that it would close the subsidiary over the data privacy backlash.[11] Its file [AvastUI.exe] cannot be task killed even through the highest premmissions.
