Troubleshooting

How can I disable third-party ads in Avast One for Android?
To support the ongoing development of Avast One, the free version of the app includes third-party ads that do not interfere with app usage. Paid versions of Avast One are ad-free and include a range of additional premium features and benefits. Subscribe to a paid version of Avast One by tapping Upgrade in the top-right corner of the main app screen.
What should I do if the Accessibility permission is disabled repeatedly?
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.
How can I reset the PIN for App Lock?
For information about resetting the App Lock PIN, refer to the following article: New Avast One - Getting Started.
What should I do if Avast One for Android crashes or stops running?
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.
What can I do when Avast One for Android cannot remove malware?
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.
How can I report a false positive detection to Avast Threat Labs?
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:
- Tap
⋮More options (the three dots) next to the detected file that you want to report. - Tap Not malware.

How can I disable sound alerts for background notifications from Avast One?
On some Honor or Huawei devices, a sound plays each time you receive a notification from Avast One. To prevent this, follow the steps below on your Honor or Huawei device:
- Open your device Settings and go to Apps & notifications.
- Select Notifications management.
- Tap Avast One for Android, then select Background services.
- 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.
Why does Avast One need so many permissions?
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.
How can I report an issue to Avast Support?
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.
