Trojan.Gamarue, Gamarue


Trojan:W32/Gamarue is a family of trojans that use the infected computer to send out spam email messages. Specific variants may also perform other malicious actions.


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

Gamarue variants typically arrive as attachments to spam email messages. When the attachment is run, the trojan is installed on the machine, where it may, depending on the specific variant:

  • Use the system's resources to send out spam
  • Download and install other malware
  • And copy itself to removable media

Older variants of Gamarue may also be technically classified as Worms.
