Summary

The LIBERTY.A is a simple trojan written for the 3COM Palm platform. When activated, the trojan deletes all application files on the device.

Removal

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

The trojan pretends to be a crack for Liberty Gameboy emulator 1.1, and is shown as Crack 1.1 icon in the palm screen.

On a PC, the Trojan will appear as a file called "liberty_1_1_crack.prc" with a size of 2,663 bytes.

When a user tries to execute the application, the trojan is activated and it attempts to delete all application files on the device and then reboot it.

This file is a trojan, not a virus, so it cannot replicate itself into any other files, and it does not transfer automatically.

To remove the trojan from the palm device, select the delete option from the app menu (click menu button when on applications screen), and delete the Crack 1.1 application.

To remove the trojan from PC, please use F-Secure Anti-Virus.

If you have activated the trojan and lost files, the files can be restored by setting all HotSync conduits to 'Desktop overwrites handheld' and hotsyncing with the Palm desktop. The hotsync conduits can be set at the HotSync/Custom menu at the Palm desktop.

F-Secure Anti-Virus detects the trojan with the updates since August 30, 2000.
