Summary
Trojan:SymbOS/Singlejump is a family of trojans that infect devices running the Symbian operating system. On execution, variants in the family replace built-in and third party applications on the device with components that reset the phone if launched.
Removal
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.
Technical Details
Propagation
Singlejump variants also use variants from the Bluetooth-Worm:SymbOS/Cabir family to distribute other trojans to new victim devices. The Cabir worm is started automatically when the malware is first installed; if the device is rebooted, the Cabir worm will simply start again.
Instead of sending a copy of itself, the Cabir variant loads the SIS file installed by Singlejump and sends it to the first phone it finds within Bluetooth range.
In most cases, these trojans doesn't send themselves further than a single new victim, so its quite obvious how this malware got its name.
