New Avast One - FAQs

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.

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.
• Purchase, activate, and manage Avast apps directly within the same application.
• Customize your setup based on personal needs and subscription preferences.

Avast One for Android is a security app that helps protect your mobile device from unwanted phishing, malware, spyware, and malicious viruses such as trojans. It also helps secure your email accounts and accounts associated with your email addresses, lock your sensitive apps, and protect access to your photos stored on your device.

The new Avast One app for Android is replacing both the previous Avast One app and Avast Mobile Security. As part of this change, the older Avast One and Avast Mobile Security apps are being removed from the Google Play Store. All new installations on Android install the new Avast One app.

How this affects you depends on which app you currently use:

• Avast Mobile Security users: If you have Avast Mobile Security installed, your app is updated automatically to the new Avast One through Google Play. Your protection continues in the new app after the update.
• Existing Avast One users (legacy Avast One): If you previously used the legacy Avast One app and have an active Silver, Gold, or Platinum subscription, you are prompted to install the new Avast One app. After signing in to the new app with the Avast Account that contains your subscription, or restoring the purchase from the Google Play Store, the corresponding paid features are enabled.

This can happen if you had the legacy Avast One app installed and then installed the new Avast One app without removing the legacy one. The legacy app no longer receives updates, and we recommend removing it after the new app is set up.

Avast One helps protect your Android device from known malware and threats, and monitors data going in and out according to your preferences. We do our best to protect your device against all possible threats, but no solution is 100% effective.

Like all applications on the Android market, it is subject to limitations imposed by the operating system version running on the device. It cannot protect against exploits targeting specific vulnerabilities in the OS kernel, the network stack and other fundamental parts of the system. However, we take our role in the security industry seriously, and continuously work with Android vendors to develop future solutions to minimize the risk of attacks.

For detailed information on system requirements for Avast One, refer to the following article: System requirements for Avast applications.

Avast One supports both Android phones and tablets. The app is compatible with most ARM Android devices. However, each vendor or manufacturer makes slight changes in their devices, so some features may behave unexpectedly or, in rare cases, not work. Note that Avast cannot cover all vendor customizations to the OS. However, we gladly accept feedback if you experience compatibility issues on your Android device.

If you are using a custom ROM (Read-Only-Memory), the app may not work as expected. If you have any feedback regarding this issue, report it to Avast Support.

Avast One is not supported by and cannot be installed or run on:

• Symbian, Microsoft Windows Phone/Mobile, Bada, WebOS, or any mobile operating system other than Android. The iOS version of Avast One can be downloaded from the App Store.

For detailed installation instructions, refer to the following article:

• Installing Avast One

For detailed activation instructions, refer to the following article:

• Activating premium Avast One features

There are three tiers of paid Avast One subscriptions: Basic, Premium, and Ultimate.

• Basic: Includes Automatic Scan, Hack Alerts, Unlimited Photo Vault, App Lock, and direct customer support.

  The Basic tier is available for purchase only during initial on-boarding, after installation.

• Premium: Includes everything in the Basic tier, plus Email Guard, SMS Guard, Call Guard, and Link Guard.
• Ultimate: Includes everything in the Basic and Premium tiers, plus VPN. It can also be used to activate Avast Cleanup and Avast SecureLine VPN.

In addition, existing Avast Mobile Security subscriptions (Premium and Ultimate) remain valid and can be used to activate the corresponding Avast One tiers.

The following subscriptions can also be used to activate corresponding features in Avast One: Avast Premium Security Multi-device activates all features included in Avast One Premium, Avast Ultimate Multi-device activates all features included in Avast One Ultimate, and Avast SecureLine VPN provides access to VPN features only.

To upgrade Avast One to one of the paid versions, tap Upgrade in the top-right corner, select your preferred subscription tier (Avast One Premium or Avast One Ultimate), then follow the on-screen instructions to subscribe. When the transaction completes, the paid version of Avast One activates automatically on your Android device. Your purchased subscription is valid on devices that are connected to your Google Account and have Avast One installed.

The paid versions available may differ according to your region and certain regulatory restrictions. You may see some or all of the subscription packages Avast offers.

Avast One Basic and Avast One Premium are valid only for use within the Avast One app. Avast One Ultimate can also be used to activate Avast Cleanup and Avast SecureLine VPN.

When you upgrade from one paid version of Avast One to another (for example, from Avast One Premium to Avast One Ultimate), Google Play Store automatically calculates how much of your original subscription was unused. To compensate you for the value of this unused subscription, you receive access to the upgraded subscription for a period of time that is equivalent to the value of that unused subscription at no extra cost. This means you are not immediately charged when you activate your upgraded subscription, but when that period ends (unless canceled first). The length of that access period depends on how much of your original subscription was unused. The date of your first payment is displayed during the subscription upgrade.

To start using your Avast One subscription on another device, refer to the following article: Transferring or restoring Avast mobile subscriptions.

Uninstalling the paid Avast One app from your Android device does not cancel your subscription. You will continue to be charged until you cancel it. For information on how to cancel a subscription purchased via the Play Store, refer to the following article: Canceling an Avast subscription via Google Play Store or the App Store.

If you did not subscribe to your paid version of Avast One using the Google Play Store, you need to cancel the subscription via your Avast Account. For detailed instructions, refer to the following article: Canceling the renewal for a subscription via your Avast Account.

In rare cases, Avast One does not detect your valid subscription and displays the No subscriptions found message when you try to restore your subscription. For instructions on how to resolve this issue, refer to the following article: Troubleshooting activation issues in Avast mobile apps.

The Run Smart Scan button on the main app screen scans apps installed on your device and alerts you to potential security risks, including issues caused by changes to default settings.

Avast One automatically scans newly installed apps the first time they are run. Avast One offers to uninstall the app or delete the file if malware is detected. If an app or file is incorrectly identified as malware, you can report the false-positive detection directly to Avast Threat Labs.

To schedule automatic scans, refer to the following article: New Avast One for Android and iOS - Getting Started.

Scam Guardian within Avast One offers several features to help verify website legitimacy and reduce the risk of fraudulent interactions.

For more information about using Scam Guardian and the features within, refer to the following articles:

• Avast One Scam Guardian Pro - FAQs
• Avast One Scam Guardian Pro - Getting Started

For more information about using Junk Cleaner, refer to the following article: New Avast One for Android and iOS - Getting Started.

Wi-Fi Speed test measures and rates your network's current download and upload speeds. It also scans your network for problems with your router, encryption, Wi-Fi, and connection. When this action is complete, the app advises whether the network you are connected to is safe. Any detected issues are described, along with instructions on how to resolve them.

App Lock is a paid Avast One feature that helps protect most of your sensitive apps using a PIN or pattern. If your device supports fingerprint unlocking, you can also use a fingerprint to unlock apps protected by App Lock.

For information about enabling this feature refer to the following article: New Avast One for Android and iOS - Getting Started.

Photo Vault allows you to protect access to your photos stored on your device with a PIN code. Photos that are moved to Photo Vault are encrypted and hidden.

To learn how to use Photo Vault, refer to the following article: New Avast One for Android and iOS - Getting Started.

App Insights provides you with usage information about the apps on your device, and allows you to view which permissions are required by your installed apps.

The VPN feature in Avast One is only available if you have an Avast One Ultimate or an Avast SecureLine VPN subscription.

The VPN feature allows you to connect to the internet via Avast VPN servers, using an encrypted tunnel to help protect your online activity from eavesdropping. VPN in Avast One offers:

• Protection: When many people are connected to the same public network, attackers can capture sensitive data, such as logins and passwords. The encrypted VPN connection provides adequate protection against these types of attacks.
• Anonymization: With broadband connections, many people have fixed IP addresses, which can be tracked when browsing sensitive sites. With a VPN connection, the browsing session is effectively anonymized, as the IP address the remote server sees is the address of the VPN server, not the user.
• Access content around the world: Using a VPN allows you to access servers in different parts of the world.

For information on using VPN, refer to the following article: New Avast One for Android and iOS - Getting Started.

The VPN feature in Avast One for Android and the Avast SecureLine VPN app offer the same functionality.

The main difference is how the service is delivered. Avast SecureLine VPN is available as a standalone application focused only on VPN functionality. In contrast, Avast One includes SecureLine VPN as part of a broader security and optimization solution that combines multiple features (such as device protection, performance tools, and identity protection) within a single app.

Avast One VPN is available only with specific subscriptions. If you cannot access the VPN, ensure you have one of the following:

• Avast One Ultimate for Android
• Avast One Ultimate Multi-Device
• Avast SecureLine for Android
• Avast SecureLine Multi-Device

For information about activating a paid subscription, refer to the following article: Activating premium Avast One features.

Avast One on Android includes advanced VPN features such as Kill Switch, Auto Connect on unsecured networks, VPN protocol selection, Split Tunneling, advanced server options (P2P‑Optimized, Double VPN, and IP Rotation), Ad Tracker Blocking, and the option to refresh your IP address. For setup instructions, refer to the following article: New Avast One for Android and iOS - Getting Started.

Kill Switch blocks all internet traffic if the VPN connection unexpectedly disconnects. Traffic remains blocked until the VPN reconnects or you turn off Kill Switch. Local devices are not accessible while Kill Switch is enabled.

This happens when Auto Connect is enabled. Auto Connect automatically turns on the VPN when you connect to an unsecured network. You can manage trusted networks in the Auto Connect settings.

Yes. On Android, you can use Split Tunneling to choose which apps use the VPN connection and which bypass it.

The default protocol is suitable for most scenarios. If you experience connection or speed issues, you can select a different protocol in the VPN settings.

These are advanced server options designed for specific use cases. P2P‑Optimized servers are intended for peer-to-peer (P2P) sharing. Double VPN routes your connection through two servers for enhanced privacy. IP Rotation regularly changes your IP address to help reduce tracking and location-based restrictions. Using these servers may affect connection speed.

Subscribe to a paid version of Avast One by tapping Upgrade in the top-right corner of the main app screen.

To improve performance, some Android devices force apps to stop when your device screen turns off. This often causes apps with the Accessibility permission to lose this permission.

To re-enable the Accessibility permission, open your device settings, search for Accessibility, then grant this permission to Avast One.

We recommend changing your system settings to prevent Avast One from losing the permission. For detailed instructions, refer to the following article: Preventing your Android device from stopping Avast apps.

For information about resetting the App Lock PIN, refer to the following article: New Avast One for Android and iOS - Getting Started.

Try one of the following options:

• Fully uninstall, then reinstall Avast One.
• Report the issue to Avast Support so that our support representatives can perform a deeper analysis.
• Join the Avast Beta program to test the latest versions of Avast Android apps before public release. This means that you receive app updates and bug fixes earlier.

In rare cases, Avast One detects malware but cannot uninstall it. This is usually caused by the level of permissions granted to the suspicious app or the app being installed as a system app. For more information, refer to the following article: Resolving a malware removal issue in Avast One.

In rare cases, Avast One may detect and mark a clean file as malware. You can report false detections to Avast Threat Labs directly from the scan results screen:

1. Tap ⋮ More options (the three dots) next to the detected file that you want to report.
2. Tap Not malware.
3. Type a description of the issue.
4. Tap Send.

1. Open your device Settings and go to Apps & notifications.
2. Select Notifications management.
3. Tap Avast One for Android, then select Background services.
4. Tap the blue (ON) slider next to Ringtone, so it changes to gray (OFF).

A sound no longer plays each time you receive a notification from Avast One.

Avast One for Android requires many permissions that may initially seem unnecessary. This is because permission classifications in Android are assigned a name based on the most common use case, but do not describe all the kinds of processes that require the permission. For example, the full internet access permission is required to receive updates to malware definitions, and Scan and Web Guard need permission to read phone data so the data can be scanned for threats.

We take your privacy very seriously. The permissions requested are the minimum set that is needed to implement the functionality of Avast One for Android. For more information, refer to the following article: Permissions required by Avast One.

We offer many self-help articles on the Avast Support pages. However, some issues may require deeper investigation by Avast Support.

If you have a paid subscription to Avast One, you can contact Avast Support. Our support agents will help you resolve your issues.

Avast One for iOS is an app designed to protect your privacy online, securely store your photos, block dangerous websites, and alert you if your online accounts or email addresses have been leaked online. It also helps secure your email accounts and accounts associated with your email addresses and protect access to your photos stored on your device.

The new Avast One app for iOS is replacing both the previous Avast One app and Avast Mobile Security. As part of this change, the older Avast One and Avast Mobile Security apps are being removed from the Apple App Store. All new installations on iOS install the new Avast One app.

How this affects you depends on which app you currently use:

• Avast Mobile Security users: If you have Avast Mobile Security installed, your app is updated automatically to the new Avast One through Apple App Store. Your protection continues in the new app after the update.
• Existing Avast One users (legacy Avast One): If you previously used the legacy Avast One app and have an active Silver, Gold, or Platinum subscription, you are prompted to install the new Avast One app. After signing in to the new app with the Avast Account that contains your subscription, or restoring the purchase from the Apple App Store, the corresponding paid features are enabled.

This can happen if you had the legacy Avast One app installed and then installed the new Avast One app without removing the legacy one. The legacy app no longer receives updates, and we recommend removing it after the new app is set up.

The VPN feature in Avast One is only available if you have an Avast One Ultimate or an Avast SecureLine VPN subscription.

The VPN feature allows you to connect to the internet via Avast VPN servers, using an encrypted tunnel to help protect your online activity from eavesdropping. VPN in Avast One offers:

• Protection: When many people are connected to the same public network, attackers can capture sensitive data, such as logins and passwords. The encrypted VPN connection provides adequate protection against these types of attacks.
• Anonymization: With broadband connections, many people have fixed IP addresses, which can be tracked when browsing sensitive sites. With a VPN connection, the browsing session is effectively anonymized, as the IP address the remote server sees is the address of the VPN server, not the user.
• Access content around the world: Using a VPN allows you to access servers in different parts of the world.
