A program that saves and installs another file (usually a harmful program) onto a computer or device.
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.
A trojan-dropper as a carrier or delivery vehicle for the file that is to be dropped, which is referred to as the dropper's payload. The payload is usually stored in the dropper's body as a compressed file.
When the trojan-dropper is run, it extracts the compressed file from its body and drops it, or saves it onto the computer or device. The trojan-dropper may also run the dropped file to install it onto the computer or device.
A trojan-dropper can drop more than one file as its payload. Many trojan-droppers will also drop images or videos, which are used as decoys and displayed to the user to distract them from any overt actions that the other dropped files may perform.
The following are representative examples of trojan-droppers:
