This is a very small but dangerous DOS-based trojan program. When it is run, it analyzes the command line and if a valid drive and directory is found, it deletes the specified directory and all its subdirectories. Files with all attributes are deleted in the Attacked folder.

Removal

Automatic action

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.

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

If no command line is specified the trojan outputs a message: "Requires more memory to run" If path specified in command line is not found the trojan outputs: "Out of memory error. Please reboot" If a trojan fails to delete any file (for example shared Windows file) in attacked folder it outputs: "Could not attack " and a file name.

After the first failure the trojan exits to system (and this saves the rest of data). If the trojan is run with "C:\" command line it will wipe most of data on the disk in a few seconds.
