What is Avast One?

Avast One is an all-in-one digital guardian that allows you to access and manage multiple Avast applications. It is designed to simplify your experience by consolidating various security, privacy, and performance tools into one customizable platform.

Through Avast One, you can:

• Install and launch your Avast apps from one place.
• Customize your app lineup based on your personal needs and available subscriptions.
• Access both free and premium features, depending on the app and subscription status.

What is the difference between the old and the new Avast One?

The previous version of Avast One offered a fixed set of features by combining selected tools from various Avast applications into a single package. It was designed to provide general protection and included a predefined selection of security, privacy, and performance tools.

The new version of Avast One introduces a more flexible and modular approach. Instead of bundling tools together, it acts as a central interface where you can:

• Choose which individual Avast apps to install and use.
