Trojan-Downloader:Android/RootSmart forwards device details to a remote server, and downloads and installs additional applications onto the compromised 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.
RootSmart disguises itself as a application whose Chinese-language name translates as 'Quick System Settings'.
Upon starting up, RootSmart connects to and forwards details of the device - including the International Mobile Equipment Identity (IMEI) and International Mobile Subscriber Identity (IMSI) number - to a command and control (CnC) server, from which it also downloads and installs additional applications.
The malware also connects to a remote location to obtain files and scripts used for gaining root access on the compromised device and installing additional malicious components on the device.
This malware is discussed in further detail in: Q1 2012 Mobile Threat Report (PDF).
