This detection from the F-Secure Security Cloud identifies a program with code or behavior that matches a known threat, Trojan:Android/Androrat.
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.
F-Secure's Security Cloud is an online service that tracks the security reputation of common programs, files and websites. If a questionable program or file is found during a scan, your F-Secure security product will send a query to the Security Cloud to get its most recent reputation rating. The product will then use that information (and if needed, further analysis) to choose whether to block, quarantine or remove the program or file.
The Security Cloud rating for the program or file indicates that it has code similar to the AndroRAT toolkit.
From the F-Secure Mobile Threat Report Q3 2013:
In July [2013], there were reports of a new toolkit (aka "binders") that simplify the process of inserting malicious code into legitimate Android apps. The binder, named "Androrat APK binder", is used to insert an existing remote access tool (RAT) known as AndroRAT, into a "carrier" app, trojanizing it.
Once the carrier app is installed onto a device, the implanted AndroRAT allows an attacker to remotely control it and among other things, monitor and make calls and messages, activate the camera and microphone, and access stored files.
