Dllhost.exe process consumes 100% CPU usage

1 Create a BAT file that shuts down the IIS service process, which can be resolved in a timely manner. File contents: net stop iisadmin/y
2 Create a boot service process of the bat file, shut down the service can start the file content in time: Net start W3svcbbs
3 problems encountered: Because the Dllhost process is too high CPU, may sometimes the operating system can not completely shut down the WWW service, so if you find that there is still a process CPU occupancy rate of 100%, you can do another shutdown process operation, and then start the WWW service.
4 One thing I haven't tried, if you put these two programs into a service, and then run when you encounter situations, it is not possible to solve the problem remotely, but the service www is not possible, because you can only close, or put the shutdown here and then set the file password, It's a good idea to start with 3389 again.

dangerous Dllhost.exe.

As a system process, because each Windows system (Win 2000 and later) has this Dllhost.exe program file, so some Trojan virus also attempt to use the same name to deceive users. However, there can be no more than two files of the same name in the same directory, so they are usually not in the directory location described above, which is most likely a malware or Trojan program file. Also do not rule out that some virus will replace the correct directory in the system Dllhost.exe files, this will often damage the system function, when you need to use it, you may have Dllhost.exe error.

FAQ: If Dllhost consumes too much memory or 100% CPU usage, it is usually related to the IIS service or the defective COM + DLL. In this case, we can prevent the IIS service or some running Dllhost.exe instances from being excluded

difference between shock wave and Dllhost.exe

The Shock wave (the killer) just took a cynical approach. In Task Manager you can view-select columns-Image path names
To see the path and source of the document to determine whether it is "infected shock wave (killer)" "cynical." So the typical feature of the infection Shock wave (killer) is not the Dllhost.exe in the process, but the RPC service problem (shockwave) and the system32\WINS directory where Svchost.exe and Dllhost.exe files (Blaster Killer) appear.
NOTE Path!!!
Dllhost.exe is the main process for COM +. Normal should be located inside the system32 directory and the System32\dllcache directory.　And there is no Dllhost.exe file in the system32\WINS directory. The file is a virus in the C:\Program Files\Microsoft Office\media\dllhost.exe.
In Vista and Windows7 systems, this file will be C:\Windows\winsxs\ in this directory.
