This trojan-downloader attempts to connect to a remote server and download additional files onto the affected machine.


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

This trojan-downloader is falsely distributed as an update for the Flash Player, in an unsigned executable file with the name "update.exe".

On installation, the malware attempts to connect to a remote server and download additional files onto the infected machine.

The remote server the malware contacts is known to be part of a botnet. At the time of writing however, the malware's file download behavior is inactive, possibly due to the remote server being taken offline.
