Trojan:Android/SMSLoader silently sends out SMS messages to multiple premium-rate numbers, while displaying a fake progress bar to distract the user.
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 detection database 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.
Trojan:Android/SMSLoader is distributed as an application named 'Fail_Android.'
Upon execution, it displays a progress bar to indicate that a file is being downloaded, along with a misleading message. In the meantime, it silently sends out SMS messages with the content "5+125 7-14-654-13233359428100" to multiple premium-rate numbers.
