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

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
