F-Secure Mobile Anti-Virus is capable to detecting and deleting the Bootton.E trojan. It can be also removed by uninstalling it with Symbian application manager.
Disinfection for the cases when phone is already rebooted and cannot start up
CAUTION! This method will remove all data on the device including calendar and phone numbers
In its structure Bootton.E is quite similar to SymbOS/Bootton.C. With the exception that instead of replacing system files with corrupted binaries the Bootton.E uses application that causes device to reboot.
In the device that is infected with Bootton.E, executing reboot application reboots device immediately. Installed corrupted system components cause reboot to fail. Thus leaving phone in unusable state after reboot.
F-Secure Mobile Anti-Virus for Symbian detects this malware starting from the update build number 44.
