What makes Avast the best free antivirus for Android?
If your phone gets stolen, you can track its location and also lock it or remotely wipe it to protect your sensitive personal data. If your device is already infected with malware, remove the threat quickly with our free virus removal tool and malware removal tool.
Why do Android devices need antivirus protection?
Avast Mobile Security for Android also protects your phone with automatic Wi-Fi network security checks. And should your phone or tablet get stolen, we’ll help you lock your device, wipe any sensitive data, and track its location.
Why isn’t Android’s built-in antivirus enough?
- Android can quickly check if apps are safe, but it’s not a reliable antivirus solution against new and emerging threats.
- Android runs apps in an isolated “sandbox” where they can’t access other portions of your device without your permission. But many people accidentally give apps more permissions than they need, and this can allow malware to spread across your device.
- Malicious apps sometimes make it onto Google Play, where they’re downloaded by thousands of people before they’re caught. Unofficial app storefronts are often less-secure than Google Play, which increases your risk.
Will Avast Mobile Security impact my phone’s performance?
Upgrade to Avast Mobile Security Premium or Ultimate straight from your app to access premium features such as App Locking, VPN, and much more.
