SVC host is not a virus, it is a part of Windows.

If you are getting svc host taking up a lot of memory or cpu, and you are using Sophos antivirus, this is probably a problem related to the new version of Sophos, go to the Sophos website to fix this.

If you dont have a problem, and are just wondering what it is, then dont delete it, it is required.

Process File: svchost or svchost.exe
Process Name: Service Host Process
Description: The Service Host Process is generic host process for services that are run from dynamic-link libraries (DLLs)
Common Errors: N/A
System Process: Yes

Man, every post has to have the all-confusing, endless list of spyware removers in the hope that one of the links will earn some points. Unfortunately, most of the time it's not the right answer and half of those listed programs are useless junkware.


That being said......

The following information is from one of 3 excellent startlist sites on the Internet. This is a description from Answersthatwork.com.
As you'll see svchost.exe can mean many things depending on where in your system it's located.

1. Service Host – Generic Host Process for Win32 Services. Windows 2000/XP only. SVCHOST is a generic process which acts as a host for processes that run from DLLs rather than EXEs. At startup SVCHOST checks the Services portion of the Registry to construct a list of DLL-based services that it needs to load, and then loads them. There can be many instances of SVCHOST running, as there will be one instance of SVCHOST for every DLL-based service or grouping of services (the grouping of services is determined by the programmers who wrote the services in question). Under Windows XP Professional you can find out what DLL-based services SVCHOST is running by typing Tasklist /SVC at a Command Prompt (MS-DOS Prompt – this command is not available in Windows XP Home), while under Windows 2000 you need to use the TLIST –s command from a Command Prompt (MS-DOS Prompt).

Recommendation :
An integral part of the operating system, leave alone – multiple instances of SVCHOST is a normal occurrence. If you experience SVCHOST errors, the problem is most likely not with SVCHOST but with the DLLs it is hosting.

2. Many viruses masquerade themselves as SVCHOST to escape detection. Some have names that are similar, such as SCCHOST, while others actually drop a program file called SVCHOST in the Windows or Windows System directory.

Recommendation :
The first recommendation is a simple one : always have a good antivirus product which is regularly updated (automatically preferably) and always renew your updates subscription when it expires. To detect if you have a virus that calls itself SVCHOST, first see if it shows up in Starter – if it does, then it is almost certain you have a virus. Secondly, if you have Windows 95/98/ME rather than WinNT4/2000/XP, then it is almost certain you have a virus. Thirdly, go to "Control Panel \ Administrative Tools \ Services" and look for any of the following services – if you find any of them, then you probably have a virus : System Important Message service
