svchost.exe

File Name: svchost.exe
Usefulness Rating:
The Svchost.exe process (Generic Host Process for Win32 Services) is an integral part of Windows OS. It cannot be stopped or restarted manually. This process manages system services that run from dynamic link libraries (files with extension .dll). Examples for such system services are: "Automatic Updates", "Windows Firewall", "Plug and Play", "Fax Service", "Windows Themes" and many more.
Other instance of svchost.exe:
Because the svchost.exe process is used as a common system process, some malware often uses a process name of "svchost.exe" to disguise itself. Determining the image path of a process, and its invoking command line, can help identify software masquerading in this way, and help locate the actual program file which is running under the assumed process name of "svchost.exe" (MS Windows allows multiple processes to all display the same name). Some malware inject a .dll file into the authentic svchost process, for example Win32/Conficker worm.
Recommendation:
It is not recommended to stop or remove the svchost.exe process. If the process svchost.exe uses high cpu resources, it is mostly because the service "Automatic Updates" is downloading some new Windows update. But having a 99% or 100% cpu usage could be caused by downloads due of some hidden malware on your computer. Some malware like the Conficker worm changes the Windows Registry so that svchost loads the malware .dll file. In this case you only see the authentic svchost.exe process in the task manager! Use malware removers to remove this immediately.

O Svchost.exe é um processo de host do windows não deve ser finalizado, pois é muito importante... Normalmente ficam de 4 a 7 processos no computador...mais de 7 pode ser virús, menos de 4 normal, mas é difícil de acontecer... O ùnico problema é que muitos virús se ocultam nele... E vão cada vez mais aumentando o número de Svchost's.exe

I have TWELVE copies running right now. This can't be normal. Anything I can/should do? (They are all in the correct directory so they are the real deal.)

I understand that this is a standard Windows component, but one instance of it is permanently using 98 - 100% CPU. Killing it manually from Task Manager seems to be the only way to get the PC running again. Curiously, this does not happen when I change the user to have Administrator priveleges - then 99% CPU is System Idle (as it should be). But it is too much of a security risk to leave it that way, so I change it back to a Limited user and can't do any work until I kill svchost again. This is all happening in XP Pro, so I can't use Gennessis' suggestion for identifying the offending service. Using "tasklist /SVC" shows the offender as "N/A". Can anybody offer any other suggestions?
