What is Avast Mobile Security?

Avast Mobile Security 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.

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 your online accounts or email addresses have been leaked online.

How does Avast Mobile Security help protect my device?

Avast Mobile Security 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.

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 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 Mobile Security for Android. For more information, refer to the following article: Permissions required by Avast Mobile Security.
