The original Dllhost.exe is a legitimate Windows file

Dllhost.exe is a legitimate process, which belongs to Microsoft Windows Operating System.This executable process is popularly known as COM surrogate, which manages DLL based applications. Besides, it works for controlling the operations in Internet Information Services (IIS), loads the .NET runtime and does other activities. Mostly, the size of this file is about 5,120 bytes, and it is located in C:\Windows\System32 or C:\Windows\winsxs folder.

The dllhost.exe file launches automatically as soon as Windows starts. We don’t recommend terminating this program because it’s important for the stable and secure computer‘s work. Alternative names for this process are dllhost.exe *32 or dllhost.exe *32 COM Surrogate.

Usually, there is no need to remove Dllhost processes because they are essential for the operating system to function smoothly.
