If the file is 26,624 bytes then its not a virus, else it is

Userinit.exe is an application that runs logon scripts in Windows, but it IS possible to bypass using it and still use your computer. In the registry HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon there is a Userinit entry; change this to CMD, Powershell, or Taskmgr to bypass userinit.exe until you are ready to run it. I have my computer set to run Windows Powershell ISE instead of Userinit on logon, and it works fine. If the file is infected, that's not Windows' fault - the file alone is safe and essential - but it can be temporarily quarantined for repairs by choosing a different executable to load on logon.
userinit.exe is a key process in the Windows operating system. On boot-up it manages the different start up sequences needed, such as establishing network connection and starting up the Windows shell. This program is important for the stable and secure running of your computer and should not be terminated. userinit.exe is a system process that is needed for your PC to work properly. It should not be removed.
when userinit.exe does not exec, my win7 fails to show desktop.
I have report that my friend detected as a virus under System32. Once it was deleted, she is stuck at the window Logon screen with the user avatar etc. Everytime it is clicked, the laptop proceed to shutdown instead of logon.
I deleted it after reading it was 55% dangerous. The computer could not be started and I had to reinstall from my back up

Userinit is a useful application. Never delete it. It must be only in the system32 folder in windows and also in the startup folder.
Its a virus whenever you connect an internet this makes connection disconnected withing a few seconds after connecting internet. you need to delete all tmp files from %temp% folder some files can not be deleted but you have to delete forcefully any how this files after the removal of the file you can get rid out from the virus.

Best practices for resolving userinit issues

A clean and tidy computer is the key requirement for avoiding problems with userinit. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
