Singlejump.K is Symbian SIS file trojan that replaces system files and some third party applications with corrupted binaries from other symbian trojans. These components cause the device to reboot if executed and prevent the phone from booting, so if your phone is infected with Singlejump.K, it is critical not to reboot the phone. Singlejump.K also sends SymbOS/Mabir.A to the first device it finds over Bluetooth.
