General

What is Avast Mobile Security?

Avast Mobile Security for Android is a security app that protects mobile devices from unwanted phishing, malware, and spyware, as well as malicious viruses such as trojans. In addition, the embedded Anti-Theft feature allows you to locate and track your lost or stolen device on a map with our web-based mobile tracking that uses GPS and other triangulation methods.

Avast Mobile Security for iOS is an app designed to protect your privacy online, securely store your photos, block dangerous websites, and alert you if any of your personal data linked to your email address has been leaked online.

How does Avast Mobile Security protect my device?

Avast Mobile Security protects 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 products on the Android market, it is subject to limitations imposed by the operating system version that is 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.

How is Avast Mobile Security for Android different from Avast Premium Security for desktop computers?

The Scan feature and the Shields included in Avast Mobile Security for Android use different definitions than the ones used in our antivirus software for PCs. The app is customized to run on mobile devices, and so the definitions are specific to malware that attacks mobile platforms. This saves your device from being overloaded by our PC antivirus engine, which includes an enormous amount of malware data that is not relevant to your mobile device.

How much battery does Avast Mobile Security use?

Avast Mobile Security for Android is designed to have minimal impact on battery life. Testing across multiple devices shows that all services by this app generally take up less than 5% of battery consumption (by comparison, the Launcher can take up about 15% and Gmail about 8%). Avast Mobile Security can reach maximally 20% battery usage at the peak of CPU use (about 30-60 seconds).

What happens if I upgrade from my current subscription to a different subscription?

To compensate you for the value of this unused subscription, you receive free access to the new paid product for a limited time period. This means that you are not immediately charged when you activate your new paid subscription. The length of your free access period depends on how much of your original subscription was unused. When the free access period ends, your new paid subscription automatically begins and you are charged for your chosen subscription plan (1 year or 1 month). The date of your first payment is displayed during the subscription upgrade.

Why has the Firewall feature been removed from Avast Mobile Security for Android?

The Firewall feature in Avast Mobile Security for Android depended on access to several system features that required root privileges. Due to low usage of the Firewall feature, and the risks associated with using a rooted device, we have removed Firewall from Avast Mobile Security for Android version 6.27 and higher.

Avast does not recommend rooting. A rooted device is generally not as secure and users who choose to root their device are exposed to higher risks.

Rooting is a process that allows Android users to attain privileged control of their device (known as root access) within the Android system. Rooting allows the user to override limitations set by carriers and hardware manufacturers. This makes it possible to alter or replace system applications and settings, and run specialized apps that require administrator-level permissions.

What is Call Blocker?

Call Blocker enables you to block calls from the following numbers or contacts:

• All unknown numbers.
• All hidden numbers.
• A chosen contact from your contacts list.
• A chosen number that you have entered manually into the app.

View a list of calls that have been blocked by tapping History in the Call Blocker menu.

What is Power Save?

Power Save allows you to adjust a range of settings that may reduce your device's battery consumption. Access Power Save by tapping ☰ Menu (three lines) ▸ Power Save. Select Activate Power Save to enable Power Save. Tap Power Save Settings to configure how your device behaves when Power Save is enabled, or alternatively use the default configuration.

What is Wi-Fi Protection?

Wi-Fi Protection (previously called Secure Browsing) uses our VPN (Virtual Private Network) infrastructure to create a secured VPN connection. This protects the data you upload and download from the internet, secures data sent from your device, and keeps your internet activity completely private. Wi-Fi Protection is available as part of an Avast Mobile Security Premium subscription.

What is Identity Protection?

VPN Protection

What is VPN Protection?

The VPN Protection feature allows you to connect to the internet via secure Avast VPN servers, using an encrypted tunnel to protect your online activity from eavesdropping. VPN in Avast Mobile Security for Android 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 effective 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: When you are connected to a VPN server in another location, you gain access to content that may be restricted in your location. This allows you to browse freely, even from countries with web censorship.

What is the difference between the VPN feature in Avast Mobile Security for Android and the Avast SecureLine VPN app?

Both the VPN Protection feature in Avast Mobile Security for Android and the Avast SecureLine VPN app allow you to connect to the internet via secure Avast VPN servers, protecting your personal data, and effectively anonymizing your online activity. When you connect to our VPN servers using the VPN Protection feature in Avast Mobile Security for Android, you can choose from the same list of server locations that is available in Avast SecureLine VPN.

The Avast SecureLine VPN app contains certain advanced settings options that are not available in Avast Mobile Security for Android, including Auto Connect and Split Tunneling. For more information, refer to the following article:

• Avast SecureLine VPN - Frequently Asked Questions

How can I add the VPN feature to Avast Mobile Security for Android?

No. In this case you would continue to use Avast SecureLine VPN as a separate app. However, the activation code from an Avast Mobile Ultimate subscription can be used to activate either the VPN feature in Avast Mobile Security or Avast SecureLine VPN (for use on up to 5 Android devices simultaneously).

How can I change App Lock timeout settings?

To specify when apps will be locked by the App Lock feature, go to ☰ Menu (three lines) ▸ Settings ▸ App Lock and tap App Lock timeout. The following options are available:

• Immediately: Locks an app immediately after you send it to the background.

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 Mobile Security.

We recommend changing your system settings to prevent Avast Mobile Security from losing the permission. For detailed instructions, refer to the following article:

Why does Avast Mobile Security need so many permissions?

Avast Mobile Security 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 does 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 Shield 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 are needed to implement the functionality of Avast Mobile Security for Android. For more information, refer to the following article:

• Permissions required by Avast Mobile Security
