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.

Chris		One of these is definitely rogue. It runs at 770 MB, ranging from 40-70% CPU usage, right after boot up. When I check the properties, it has very little information, and none of the Microsoft information that the other instances has. Yet I can\'t delete or block it. How can I find this app in my system to virus scan it and/or delete it? 19 13 Report Abuse

frickfrack		You can have many svchost.exe from 5 to 20+ depending on the number of DLLs that are running. NOTE: * The only concern about svchost.exe you need to pay attention to is CORRECT SPELLING- ANY variation will be a security issue. *Some "must" run due to required system ops. so you may not recognize or understand. Regardless, some need to run. *High CPU usage or crashes? Too many applications are running for your system. Older systems (chips,ram, memory)are being overworked. Close some apps. to see if this helps. If not, system upgrade or newer PC is needed(sorry). * Finally, consider this. I.E. was getting sluggish. So I switched to Firefox browser and like magic DLL/svchost.exe was no longer a CPU/Memory hog- no crashes, etc. svchost.exe but rather that your system is 14 0 Report Abuse
Rasmus		This is the process on witch all of your services are running. Some services might be dangerous, but then you should be worrying about the service itself, not svchost.exe. There can be several services in one svchost.exe, but it is still normal to have a lot of them running at the same time. 0 0 Report Abuse
