  • This is my analysis results of this malicious file. If you have any questions, or have any problems that cannot be resolved, you can leave a message or email me.

    • You can also use the following online detection function to check the file.
  • • Enter the file name, or file MD5, for the query.
  • • You can also scan a file online. Click the "Upload File" button, and then click the "submit" button, to immediately detect whether the file is a virus. (Tip: The maximum size of the file uploaded cannot exceed 8MB)


  • T21 can detect unknown files online, mainly using "behavior-based" judgment mechanism. It is very simple to use T21.

    1. Click the "Upload File" button, select the file you want to detect, and then click "Submit".
    2. The next step is to wait for the system to check, which may take a little time, so please be patient.
    3. When the T21 scan engine finishes detection, the test results are immediately fed back, as shown below:

    • If you suspect that there are malicious files on your computer, but you cannot find where they are, or if you want to make a thorough check on your computer, you can download the automatic scanning tool.

    If you want to know what kind of T21 system is, you can click here to view the introduction of T21. You can also go to the home page to read the original intention and philosophy of my development of T21 system.
