Singlejump.J (renamed Onehop.J) is Symbian SIS file trojan that replaces system files and some 3rd party applications with corrupted binaries from SymbOS/Doomboot.A trojan. These components prevent phone from rebooting, so if your phone is infected with Singlejump.J, it is critical not to reboot the phone.
Singlejump.J sends also SymbOS/Onehop.B to the first device it finds with Bluetooth.
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.

Singlejump.J replaces built in and third party applications with component that causes reboot to fail.
Singlejump.J use modified Cabir to spread other trojans. Instead of sending a copy of itself it loads SIS file installed by Singlejump.J and sends it to the first phone it finds within Bluetooth range.
