The Antivirus module safeguards your device against malicious code by blocking incoming threats and cleaning them.


Real-time protection

Real-time file system protection controls all files in download folders for malicious code when opened, created, or run.

By default, Real-time file system protection launches at system start-up and provides uninterrupted scanning. We do not recommend disabling Enable Real-time file system protection in the Antivirus section click the menu button three_dots_menu > Advanced settings > Real-time protection.

Scan device

Certain pre-defined file types are scanned by default. A device scan checks memory, running processes, and their dependent dynamic link libraries as well as files that are part of internal and removable storage. A brief summary of the scan will be saved to a log file available in the Scan Logs section. If you want to abort a scan already in progress, tap Cancel. Scan outcome and statistic will be displayed during the scan in the Antivirus section.


Memory card scanning

ESET Mobile Security does not support memory card scanning on devices with Android 5 and earlier.

Unresolved threats

After ESET Mobile Security detects a threat, this option will be available until you select a response action to the threat. The available response actions are to remove the threat or to ignore it.

Ignore threats

After you choose to Ignore a threat, the Ignore threats option will appear. This option will still allow you to remove an ignored threat at a later time.

On-charger scan

When this option is selected, the scan will start automatically when the device is in an idle state, fully charged and connected to a charger.

Scheduled scan

The scheduled scan allows you to schedule a Device scan to run automatically at a predefined time. To schedule a scan, tap the switch next to Scheduled scan and specify the dates and times for the scan to be launched.

Update detection modules

By default, ESET Mobile Security includes an update task to ensure that the program is updated regularly. To run the update manually, tap Update detection modules.


Data transfer charging

To prevent unnecessary bandwidth usage, updates are issued as needed when a new threat is added. Updates are free, although you may be charged by your mobile service provider for data transfers.
