Wmiprvse.exe Application Error Help

First off, let’s take a look at what Wmiprvse.exe actually is:

Wmiprvse.exe is a component of the Microsoft® Windows® operating system and is the executable for the Windows® Management Instrumentation that controls management information. By using industry standards, managers can call WMI to query and set default information on desktop systems, applications, networks and other enterprise components. Software developers use WMI to create event monitoring applications that can alert users when important actions have occured.

NOTE: Wmiprvse.exe file is located by default in the “C:\Windows\System32\Wbem” folder.

However, there is also a known worm that uses the same process name called “W32/Sonebot-B” and drops a copy of itself in the “C:\Windows\System32” folder with the filename WMIPRVSE.EXE and can set Windows registry entries to run the copy whenever your reboot your computer:

Kernel_check = wmiprvse.exe

Kernel_check = wmiprvse.exe

W32/Sonebot-B also attempts to terminate a number of processes and delete a number of files from the infected computer.

Sonet-B worm may also set the registry entries listed below:

AutoShareServer = <value>
AutoShareWks = <value>

RestrictAnonymous = <value>
RestrictAnonymousSam = <value>
