Summary
Fontal.I is a SIS file trojan that installs corrupted Font file into infected device, thus causing the device to fail at next reboot. Fontal.I also tries to disable Kaspersky Anti-Virus for Symbian, currently it is still unverified whether this attempt is successful or not.
Fontal.I pretends to be Nokia Anti-Virus for Symbian devices, when installed the Fontal.I will show following installation text:
Nokia Anti-Virus keep your phone protected from mobile virus. Please restart your phone after installation complete to activate your anti-virus product. If you found any problem regarding this software, please call :
If a phone is infected with Fontal.I, it must not be rebooted as the trojan will prevent the phone from booting again. If the phone is rebooted, it will try to boot, but will be forever stuck on phone startup and cannot be used.
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.
