The thing about Trojans is that they all are rather similar programs and their exact features depend on the files they come with and what the hacker who is responsible for managing the Trojan wants it to do. Trojan.Teniel is a rather generic Trojan that enters your computer and focuses on your own system only, instead of trying to make copies of itself and spread further. Trojan.Teniel was first discovered in September 2011, and ever since then it has infected multiple computers worldwide. Usually it targets three types of operating systems - Windows 2000, Windows XP and Windows Server 2003.

Research claims that Trojan.Teniel has backdoor features and is a part of Bitcoin mining malware. Bitcoin is a type of virtual currency that computer users exchange among themselves instead of using bank or any other payment processing service. Due to the fact that bitcoin offers anonymity and is of high value there are a lot of cyber thieves who are using Trojans and other types of malware to steal it. As far as Trojan.Teniel is concerned, when it settles down in the infected system it usually performs DDoS attacks, and then helps other malware to steal bitcoins before you remove it.

Trojan.Teniel is known to connect to a list of IP addresses without your knowledge, and then send and/or receive information (or even download more malware). With the information received Trojan.Teniel also acquires a new list of IP addresses it needs to connect to, and a list of websites that it needs to direct its DDoS attacks to.

The dangerous thing about Trojan.Teniel is that users usually download it from malicious websites without even realizing it, and once the Trojan is in, it adds a subkey into the registry, enabling the automatic Trojan.Teniel execution every single time you turn on your computer. Also, since this Trojan does not have an interface, it might take some time to realize that you are infected with something. If you suspect that something is not right, try checking for svchostdriver.exe in Windows Task Manager. It is a process file that comes together with Trojan.Teniel and it is a direct proof that the system is infected with the Trojan.

If you know how to fix your registry and delete the files associated with it, you might as well delete Trojan.Teniel on your own, but if you are not a computer expert it is better to acquire a powerful security tool and erase Trojan.Teniel automatically with a reliable computer safeguard program.
