Summary

Zhelatin.TQ, like its predecessors, is a bot that communicates via Overnet P2P protocol and is mainly used to send spam.

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

Zhelatin.TQ does the following upon initial installation:

  • Disables Windows File Protection
  • Drops its rootkit component%SystemDirectory%\diperto[random]-[random].sys
  • Drops its configuration file%SystemDirectory%\diperto.ini
  • Exits the current process

To enable execution of startup, the loader component will create a Windows service to automatically execute the driver on next reboot resulting in the addition of the following registry keys / sub keys in:

  • HKLM\System\CurrentControlSet\Services\diperto[random]-[random]

The malware then tries to communicate with the other peers via the Overnet P2P protocol on how to proceed. It is basically downloading other component/configuration details via the P2P network. The malware has the ability to do the following:

  • Harvest email addresses but avoid those that contain certain strings
  • Download messages to be used in spam
  • Send spam emails
