This page aims to help you remove Udt.exe. Our removal instructions work for every version of Windows.


Udt.exe is a Trojan horse that can spy on the user, steal passwords and login credentials, and exploit system resources. Udt.exe can infect a computer without showing visible symptoms and can remain in the system for an indefinite period of time or unless it gets detected.


The Udt.exe Trojan Virus

The Trojan horse viruses are considered to be the worst of all malware forms out there. They are extremely stealthy and are able to launch a whole range of malicious activities once they enter a given computer. Udt.exe, in particular, can remain unnoticed over long periods of time and manage to damage a system without the victim’s knowledge. Therefore, if you have this Trojan on your system, it should be your priority to correctly locate and remove it before it can do more harm than it already has. But since removing a Trojan is not an easy task, we have published a special removal guide that you can use for assistance. You will find it just below this article, accompanied by a professional removal tool for those of you who prefer to not interfere with important system files.

What issues can Udt.exe cause?

The Trojans are the most versatile pieces of malware on the Internet. Representatives such as Udt.exe, can be programmed to perform numerous malicious actions and this is one of the main reasons why these viruses are so popular and common. That’s also why it’s often very hard to determine what exactly a single Trojan might do by the time you discover it in your system.

For instance, it is highly possible that such malware can be used to steal some information from your computer. If the hackers who control it are interested in, say, some personal details, confidential correspondence, or some work-related data, with the Trojan’s help, they can access the said data without your knowledge. What is more, an advanced Trojan such as Udt.exe can secretly track your keystrokes and everything you type on the infected computer. In this way, the hackers who stay behind it can obtain your passwords, login credentials, debit and credit card numbers , as well as other sensitive details.

Another common use of Trojan Horses is for espionage. Similar to the above-mentioned keystroke recording process, such malware can share your screen with hackers, make screenshots, keep track of your conversations, and even hack into your webcam and mic to record videos and audios of your surroundings. In this way, the offenders may be able to track your location, observe you, record your electronic communication, and use the information obtained for all kinds of criminal deeds that we don’t need to get into. Another frightening of use of some Trojans is the one that allows criminals to insert other malware, such as ransomware, worms, or other viruses inside targeted machines with the help of a Trojan.

Therefore, if you don’t want to end up with a computer loaded with all sorts of infections, it is best to remove Udt.exe as soon as possible. We highly recommend that you also run a full system check with reliable security software or use the professional removal tool on this site to deal with the existing infection.
