Avast One 26.8 — Release Notes

:shield: Privacy and identity

  • AntiTrack is now integrated more deeply into Avast One, with its own place in the app so you can find and manage tracker protection more easily.
    • Moving to Avast One preserves more of your AntiTrack experience. Your AntiTrack settings, license, and tracker data carry over from supported standalone and legacy product journeys.
  • AntiTrack is more connected across Avast One. You can open AntiTrack directly from the browser extension, and Avast One can detect a newly installed extension and show its status, tracker activity, and fingerprint statistics.
  • AntiTrack cleanup now reopens the browser application after trackers are removed. Your prior browser tabs are not restored.
  • Secure Identity notifications now use the intended type and severity, with alert counts aligned across notifications, the dashboard, and the portal.

:globe_with_meridians: VPN

  • VPN add-on registration and installation now handle known setup errors without interrupting the Avast service.

:link: Setup, subscriptions, and upgrades

  • Avast One can now install eligible non-freemium modules when you start from an existing Avast One Free installation.
  • Links to supported Avast One modules now work with both legacy and current URL formats.

How to install this update:

  • If you already have Avast One on Windows: Open Avast One → Menu (⋯) → Settings → Update → Click the second ‘Check for updates’ button
