CiaDoor

To manually disinfect CiaDoor backdoor, it's enough to delete the backdoor main file from the Windows directory. The file is hidden and locked, so it cannot be directly deleted and it is not visible with the normal Windows tools. Disinfection can be done by deleting all relevant registry keys (see the Details below) and rebooting the computer or by manually renaming the file and rebooting. After the system restart the backdoor main file can be deleted.

• Submit a sampleAfter 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 scanningIf 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.
