File Security is a feature for Android that checks devices for unsafe files. This feature can be accessed from the Settings menu. It must be set to On. All files placed directly on the SD card or sideloaded are checked for threats. Sideload is the process of transferring data between two local devices, such as a computer and a mobile device.

This feature is important if you’ve changed the Android settings to allow for the installation of applications that are not downloaded from the Google Play^TM Store or other official app stores. File Security detects threats prior to the app or file's installation. It also allows AT&T Mobile Security app to actively monitor:

• File system changes 
• Scan SD-card loading or sideloading threats

When a threat is identified on a device, the Security tab within the app Dashboard will turn red and prompt you to take action. In some cases, an AT&T Malware Alert pop-up may appear on your device with instructions.

You can take the following actions:

• Obtain More Info
• Uninstall
• Ignore

Note: This feature isn't guaranteed to detect or protect against all viruses and malware, and it does not automatically remove these threats from your device.
