• 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.
