is a generic host process name for services that are run from dynamic-link libraries called DLLs. This is a valid system process that belongs to the Windows Operating System which handles processes executed from DLLs. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. Multiple instances of Svchost.exe can run at the same time
. Each Svchost.exe session can contain a grouping of services. Therefore, separate services can run, depending on how and where Svchost.exe is started. This grouping of services permits better control and easier debugging. The legit Svchost.exe file is located in the %SystemRoot%\System32 folder.
If its running as a startup/shows in msconfig, this can be bad. See here
Also make sure of the spelling
. If its scvhost.exe
this a trojan. See here
