Editor's Take
Avast Antivirus & Security sits at 4.6 stars across 7.3 million ratings on Google Play, and is still building an audience.
That score is hard to fake on a utility app — it usually signals a tool that stays out of your way, does one thing well, and doesn't pepper you with upsells.
Avast Software is the publisher behind this release; we'd suggest taking a quick look at their other titles on Google Play if the style clicks with you. The last visible update lands 2026-01-30, which is a small but useful signal that the team is still shipping fixes rather than treating the app as abandoned.
