This malicious code is a 32-bit program that infects an EXE file. When the file is run or the file is loaded, the malicious code in the file is run first. Later, this malicious code also infects the following files:

Tip: There is something I must emphasize. The file names listed above are infected by malicious code. It does not mean that all files named by these names are malicious files. It is inaccurate to determine whether a file is a malicious program based on its file name.

The malicious code also infects files on the following path:

• c:\windows\system32\spreview\it-it\
• c:\windows\servicing\fr-fr\
• c:\windows\ismfiles\64bit\spellcheck\
• c:\windows\diagnostics\system\printer\sr-latn-rs\
• c:\windows\panther\rollback\boot\resources\pt-br\
• c:\windows\drivers\intel pro 2915abg_2200bg\iprolang\esn\

Tip: The code of most malicious files is fixed, rarely changed, which means, this type of malicious files regardless of which computer they are in, will copy themselves into the pre-set path, so we can go to the path listed above to find this file, and there is a great chance to find it.
Are all the files with the same file name listed above and with the same path malicious files?
Of course not. The file name is just the identification of the file. Strictly speaking, the file is modified by malicious code.

The following are methods commonly used by malicious code in order to confuse users:

• Deliberately modify their own file name to some system file name, or some well-known software name.
• Generate malicious files in the system folder or in the installation folder of some well-known software, and even name their own folder with an antivirus software name (actually the user did not install this antivirus software). In fact, these malicious files are not system files, nor part of the famous software.

For example, one of the most common system file names is: explorer.exe, and under normal circumstances, the system only has an explorer.exe process. When you open the Task Manager and find that there are two or more explorer.exe processes, it is likely the camouflage of some malicious viruses. As shown in the following figure, there are two explorer.exe processes in Task Manager.

When I find the path where the file is located, it will be clear that the real explorer.exe system file is located under "C:\ Windows\", and the malicious file that pretends to be system process is under the other path.

The running status of the loadmxf.exe file that is infected with malicious code:
Take up memory 61K
Occupy CPU resources between 40% - 56%
Run the program with the SYSTEM permissions.
At runtime, 1 Windows system files, 0 external files (not owned by the Windows system), are called
Windows system files
• File name
• Number of calling functions
• mscoree.dll
• 1
• Not owned by the windows system
• File name
• Number of calling functions
• In general, the most accurate way to determine if a file is a malicious file is to analyze its code and see what happens when these functions are called while the program is running. Does it have malicious behavior (destroying data or stealing data)? I have listed the functions called by this file and some internal data, but there is too much data, I can't show them all here. →Click here← to see the full binary code analysis page.
The following files have been identified as malicious files. Some files are variants of loadmxf.exe; some files are another type of malicious file, but use the same file name as loadmxf.exe.

It is a simple and effective way to determine whether a file is a malicious file by a hash value, which has lower false detection rate than the "static signature" method. So, if the MD5 value of a file on the computer is the same as the MD5 value listed below, then it is sure that the file is a malicious file.

This is my analysis results to the code of each malicious below, mainly provided to industry professionals who engage in the maintenance of computer security. If you are interested, you can also have a view, but it may require certain computer knowledge.

# How to repair or remove loadmxf.exe

Method 1: Manual Removal

• Reboot the system and then enter safe mode (Click here to see how each Windows version (XP/Vista/7/8/10) goes into safe mode)

• Open Task Manager and if loadmxf.exe is running, end this program.

• Show all hidden files.
Step: "My Computer" -> "Floder Options" ->"View" -> "Show hidden files, folders, and drives"

• Malicious code used to generate or infect files on the following paths, so you need to one by one go into the following path, and delete all files [  loadmxf.exe, loadmxf.jpg  ]

• c:\windows\system32\spreview\it-it\
• c:\windows\servicing\fr-fr\
• c:\windows\ismfiles\64bit\spellcheck\
• c:\windows\diagnostics\system\printer\sr-latn-rs\
• c:\windows\panther\rollback\boot\resources\pt-br\
• c:\windows\drivers\intel pro 2915abg_2200bg\iprolang\esn\

Method 2: Automatic Removal Using Tools (Recommended)

This is free virus detection software, and it can be well compatible with many well-known anti-virus software, so users do not have to uninstall anti-virus software on the computer.

It is "environmentally friendly" for computers. After downloading, it can be used by decompression and without installation. In the process of running, it will not write any information to the registry, nor create any new files to the Windows folder of the system disk. When you do not need it, you can delete it. It will not leave any spam information on your computer.

When you find your operating system is abnormal, and the file name listed above appears in the Task Manager, or there are several processes in running with the same name as the core file name, it is best to download the anti-virus software to check your system.

If you don't know if loadmxf.exe is infected with malicious code on your computer, you may also use online scan tool.

• 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)
• How do I use the T21 engine for online scanning?

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.
