Trojan:Android/Exprespam silently gathers information from the affected device and forwards the data to a remote server.
Once the scan is complete, the F-Secure security product will ask if you want to uninstall the file, move it to the quarantine or keep it installed on your device.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.

Exprespam.A places an icon on the main application menu. When clicked to launch, it will display a message.
Meanwhile in the background, it collects information such as phone numbers and contact details (i.e. names and email addresses) stored on the device. The collected information is later forwarded to a remote server, http://ftuk[...]obat.com/.
