Protection Rate96%

The displayed score is an editorial rating, not a new measured detection percentage. Judge protection using dated, independent tests for the specific operating system and product version. No security product detects every threat.

Performance Impact96%

Scan speed and background load depend on hardware, files and settings. Try normal browsing, video calls and a scheduled scan on your own device before committing. This review does not claim a comparative performance benchmark.

Features

Avast One brings free protection and paid upgrades into the same product family. For a household deciding whether to pay, the useful question is which additional tools will actually be used. A free installation and a premium subscription should not be treated as interchangeable packages.
