Trojan:SymbOS/Blankfont.C is a SIS file trojan that installs corrupted system binaries/font file. The system files dropped by Blankfont.C cause the device to fail on the next reboot. If you have installed Blankfont.C, the most important thing is not to reboot the phone and follow the disinfection instructions in this description.
CAUTION This method will remove all data on the device, including calendar and phone numbers
Trojan:SymbOS/Blankfont copies corrupted font files into the phone's memory and thus prevents the phone from loading the valid font files from ROM.
The corrupted font file installed to the phone does not cause device to crash, but if the device is rebooted it will then lose the system font and is unable to display user interface texts.
Blankfont.C installs corrupted system binaries into the C:\ drive of the phone. When the phone boots these corrupted binaries will be loaded instead of the correct ones, and the phone will crash at boot.
