Trojan-Dropper (Generic)


A generic detection has identified a program or file that has features or behaviors similar to a trojan-dropper.

Security programs use generic detections that look for broad patterns of code or behavior to identify similar programs or files. If you suspect the file was incorrectly detected, go to: Removal: Suspect a file is incorrectly detected (a False Positive)?.


Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

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.

Technical Details

A trojan-dropper is a type of trojan that drops different type of standalone malware (trojans, worms, backdoors) to a system.


Like trojans in general, trojan-droppers often rely on tricking the user into believing that the program is authentic, so that they unwittingly install the program themselves. To do this, many trojan-droppers mimic or entirely copy the style and branding of popular legitimate programs or files. Others are installed as part of the payloadd of another harmful program, such as a trojan or a worm .


A trojan-dropper is usually an executable file that contains other files compressed inside its body. When the file is run, it extracts these compressed files and saves them to a folder (usually a temporary one) on the computer. drop and execute other files designed to display games, images or messages, which serve as decoys to avert attention from malicious activities.

For representative examples of trojan-droppers, see the following descriptions:
