Avast (styled "avast!") is a name brand for a set of antivirus software developed by AVAST Software s.r.o. for Microsoft Windows, Mac OS X, Android and Linux users. The software products have a user interface available in 45 languages. The name Avast came from "Anti-virus – Advanced Set," a program developed by the company's founders.

AVAST Software s.r.o. currently produces security freeware and shareware programs under the Avast brand for personal and commercial uses on PCs, Macs, and Android devices, and as of 2013 more than 200 million devices worldwide were reported to have used Avast products. In January 2014, Avast had 15.9% of the worldwide security vendor market share.

Avast products work by utilizing the 230 million devices protected worldwide to act as sensors, finding and reporting threats from all over the globe. Threats are then automatically analyzed in the cloud, and SMS-sized updates are issued approximately every 6 minutes; the protected devices are thus kept up-to-date.
