What Is Userinit.exe?

First of all, what is userinit.exe? It is known as a Userinit Logon Application file, which is a software component of the Windows system. It is located in the C:\Windows\System32 folder or sometimes in a subfolder of C:\Windows.

Userinit.exe is the file responsible for executing the logon scripts, re-establishing the network connection, and then starting Explorer.exe. This program is very important for the stable and safe operation of the computer and should not be terminated.

Userinit.exe is a system process required for the normal operation of the PC, so it should not be deleted. The userinit.exe file is an executable file on the computer's hard drive. This file contains machine code.

If the Microsoft Windows operating system software is started on the PC, the commands contained in userinit.exe will be executed on the PC. For this purpose, the file is loaded into the main memory (RAM) and runs there as a Userinit Logon Application process.

IS Userinit.exe Harmful?

The genuine userinit.exe is a key process in the Windows operating system, so it is considered safe and it won’t pose any harm to your system. The system sometimes allocates more resources for specific tasks by generating multiple instances of a process. But this may also be a symptom of a virus or Trojan infection.

Viruses with the same file name are: Worm:Win32/VB.HA or TrojanDropper:Win32/Obitel.A (detected by Microsoft), and WORM_SILLY.FDS or TROJ_GEN.R4CCRHD (detected by TrendMicro).

Then how to recognize suspicious variants?

  • If userinit.exe is located in the C:\Windows folder, the security level is 75% dangerous. Although this file is located in the Windows folder, it is not a Windows core file. And if there is no description of the program, then this file is not a Windows system file.
  • If userinit.exe is located in a subfolder of C:\, the security level is 46% dangerous. The program has a visible window but it has no file description and the program starts when Windows starts. The userinit.exe file is not a Windows core file, either.

Then what should you do to avoid being infecting by viruses? It is recommended to run a full system scan. Here is the tutorial:
