Security programs will sometimes unintentionally identify a clean program or file as malicious if its code or behavior is similar to a known harmful program or file. This is known as a False Positive. In most cases, a False Positive is fixed in a subsequent database release.
Usually, updating your F-Secure security product to use the latest database is enough to resolve the issue. You can check by first updating your F-Secure security product to use the latest detection database updates, then rescanning the file.
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it to F-Secure Labs for re-analysis.
NOTE If the file was moved to quarantine, you will need to first collect the file from quarantine before you can submit it.
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.

A trojan-downloader is a type of trojan that installs itself to the system and waits until an Internet connection becomes available to connect to a remote server or website in order to download additional programs (usually malware) onto the infected computer.
Attackers often distribute trojan-downloaders as part of the payload of another harmful program, such as a trojan-dropper, which silently drop and install the trojan-downloader on a device.
Trojan-downloaders are also commonly distributed as disguised file attached to spam emails. The attached programs are typically labelled using legitimate-sounding program or document names, such as 'invoice' or 'accounts.exe', as a simple form of social engineering. If the file attachment is opened, the trojan-downloader is installed.
Once a trojan-downloader has been installed on a machine, it will try to contact to a remove server or website, where it can either directly fetch additional files for download, or find further instructions from the attackers on where to find the files.
For representative examples of trojan-downloaders, please see the following descriptions:
