Trojan.Win32.Offloader.ZK is a devastating computer virus from the widespread malware family known as Trojan horses. Trojan.Win32.Offloader.ZK seeks to enter the computers of its victims silently, take over their settings, and then launch different harmful processes without the user’s knowledge or approval.


A Trojan horse virus is, in general, a versatile cybercrime tool and can be used differently depending on the situation and the hacker’s goals.

In many cases, Trojans are used to steal sensitive data from the computers of their victims so that the acquired info could later be used to blackmail the attacked user, to drain their banking accounts, or to carry out other similar criminal actions.

    What is Trojan.Win32.Offloader.ZK?

    A virus like Trojan.Win32.Offloader.ZK or Altruistics would take over the whole infected system and force it to conduct tasks that haven’t been approved by the user. In this regard, one of the most popular uses of some Trojan viruses is to utilize the infection as a cryptocurrency mining tool. When the Trojan is used in such a way, it first gains control of the computer by acquiring Administrator privileges and then it starts cryptocurrency-mining processes that drain most of the machine’s resources. Any cryptocurrency that is generated in this process is automatically sent to the hackers who control the virus. Due to the excessive use of GPU, RAM, and CPU, the infected computer is likely to get severely slowed down to the point where it is practically impossible to use it normally. In some cases, especially if the machine isn’t very powerful, the presence of the Trojan and the mining processes ran by it could cause the PC to crash or its screen to freeze. Therefore, if you notice any such disturbances, it is essential to check the computer’s system for any malware that may be hiding in it.

    Is Trojan.Win32.Offloader.ZK dangerous?

    Popular use that is commonly associated with Trojan horse viruses is when the threat is utilized as a distribution tool for other popular forms of malware. One particularly common example of Trojans being used as malware-distribution tools is when a virus like Trojan.Win32.Offloader.ZK loads a Ransomware infection onto computers that it has already infiltrated. In some cases, Trojans such as Trojan.Win32.Offloader.ZK may even provide cover for new malware by blocking the antivirus on the computer and preventing the user from installing new security programs. In cases where the second virus is a Ransomware representative, this allows the Ransomware to silently encrypt the files of its victim, making them unavailable and then telling the user to pay money for their release.

    How to deal with Trojan.Win32.Offloader.ZK?

    Trojan.Win32.Offloader.ZK is a new threat of the Trojan horse family and we cannot yet tell you what the criminals behind it are trying to achieve with its help. We can, however, aid you in the removal of this infection through our guide manual that can be found below. Our suggestion for you is to complete all of the steps provided there if you have even the slightest suspicion that Trojan.Win32.Offloader.ZK may currently be inside your computer.
