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

This malware is distributed in a RAR archive file attached to an email message.

The archive file contains an executable file which may be detected as either Gen:Trojan.Heur.RP.Mq0@ayDoNAeb or Trojan.Win32.AntiAV.iup.

Installation

The executable file uses the icon of a Microsoft Word document to appear legitimate. On execution, the malware will drop a clean Word document and open it for viewing, to further deceive the user.

Meanwhile, the malware will create a registry launchpoint so that subsequently its file will be automatically run at every Windows startup:

  • HKLM\Software\Microsoft\Windows\CurrentVersion\Run common = (path of the malware)

Network connections

Once its file is active, the malware will attempt to connect to:

  • tokyonews.edns.biz

The malware may also send information to an external party by a POST to an info.php page on a remote server.
