File Name: svchost.exe Product:
Author: Microsoft Corporation Security 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.


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.

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.)

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

Sorry, I\'m Spanish.. xD svchost.exe, es un proceso de Windows, (mejor dicho, procesos) que inician los servicios de Windows. Además se encarga de abrir librerias DLL.

After reading all this I feel a little better about svc. But I\'m with Art up there, I have one that is running at 160mb and bounces between 20% and 50% cpu usage very sporadically. Could this be something disguised as ans svc process?

Gennessis,thanks for great explanation on this. There should be easier programs to clean up old files and remove them. I do this frequently, yet my disk space is hardly ever cleaned properly. Any suggestions? ta.

Obviously there are some people that need more programs running on their P.C\'s but dont know how to control which ones they need running in the background. Eg; you install software for a canon printer and theres like another dozen processes that run at startup , but you may not need that software running all the time so why not start it manually, and if it takes a little longer to startup then so what , at least you have less svhosts and resourses used to have a nicely running P.C :) P.s Nicely said Gennessis

I just wanted to thank Gennessis for taking the time to explain the svchost.exe file run process. It makes better sense now as to why there can be som many of these seem to be running at the same time. It seems that as time goes on and we begin to add more and more programs to our machine that these could be optimized a bit better. Possibly even if we could re-run the setup program for windows that it would optimize all of these different files and make the memory use and allocation a bit better. If Gennessis is still monitoring these posts I was curious as to his feedback on this. Could re-installing the latest service pack help optimize these processes? *******I don\'t want anyone reading these posts to just start a re-install process on their OS. I am thinking off the top of my head hear and am always looking for better ways to make my machine to boot faster, and run more efficiently. Just because I am asking the questing here doesn\'t means that you should do this!! *******

Very suspicious about it, but Gennessis explained it very well. Clicked on More Information under Guffe\'s reply and got Uniblue selling a registry cleaner/defragger. Scan reports 763 errors, willing to clean 15. Glarysoft reported and fixed 6 for free. Who to believe? I run Firefox & Thunderbird through Filseclab Firewall (very flexible, setable, good control & reports, blocks like a backstop) plus avast! (auto updates on net connect, even reported Glary split files as nasties - several dot file extensions) and Spybot. In three years saw only about three viruses, didn\'t check cover discs. I now have 8 svchosts running. What\'s the gamble?
