Several antivirus programs may send an alert about Trojan:Script/ObfusScript!MTB if they detect an unusual activity on the computer or web browser. It aims to identify a malicious script file that tries to exploit a weakness in the operating system or internet programs in order to infect the computer with an additional threat.

Trojan:Script/ObfusScript!MTB can perform different malicious actions by running a malicious script on the computer and attempting to duplicate an Administrator account so that it can fully dominate the infected computer and install malware that is necessary for its operation.

As you can see, Trojan:Script/ObfusScript!MTB has the ability to contaminate the infected computer further by finding security vulnerabilities.  Once fully operational, the malware is obfuscated and tries to hide its files and processes to evade antivirus programs. As such, the removal of this threat is crucial to maintaining the cleanliness and safety of the computer.

How does it infect the computer?

Trojan:Script/ObfusScript!MTB normally spreads via spam emails, infected websites, social engineering attacks, and a separate virus infection. Once it executes on the computer, several files are dropped in the System folder of Windows. Then, it creates a registry entry to run the malicious code each time that Windows runs at start-up.

Trojan:Script/ObfusScript!MTB runs a process that scans for software vulnerabilities and exploits them to further infect the computer with additional viruses. Therefore, a regular software update is necessary to protect the computer from this attack.

How does this malware operate?

Cybercriminals developed Trojan:Script/ObfusScript!MTB as a way to leverage their succeeding attacks on the infected computer. Once this virus is operational on the computer, the hackers can perform different malicious actions, including the following:

  • Collect sensitive data from the computer.
  • Scans the system for vulnerabilities and sends the output to remote attackers.
  • Download and execute additional malware from a remote location.


Detecting the exploitation of a computer by Trojan:Script/ObfusScript!MTB can be challenging, as this threat is designed to operate stealthily to avoid detection. However, there may be signs that your computer is being exploited. Sudden and unexplained system slowdowns or freezes, especially during routine tasks, could indicate the presence of Trojan:Script/ObfusScript!MTB. Unusual network activity, such as unexpected data transfers or a spike in internet usage, may also suggest exploitation.

Furthermore, changes in system settings or the appearance of unfamiliar files and processes in the Task Manager could be signs of Trojan:Script/ObfusScript!MTB at work. If the virus is part of a larger attack, you might notice unauthorized access attempts, strange behavior on your accounts, or the presence of new and unfamiliar programs on your system.
