Suspect a file is incorrectly detected (a False Positive)?

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 detection database 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.

Technical Details

Trojan:Android/Gepew variants are reportedly installed on a mobile device as part of the payload of a PC-based trojan, Droidpak. When this trojan infects a Windows system, it downloads a mobile app onto the machine and then attempts to install it onto any Android devices connected to the system by a USB cable. For installation to be successful, the device must have the setting 'Enable USB debugging' enabled.

When installed, Gepew will scan the device for installed apps associated with South Korean banks. If found, Gepew prompts the user to remove these apps; if complied with, trojanized versions of these apps are installed. The trojan may also monitor and intercept incoming SMS messages, which are forwarded to a remote server. For more information, see:
