Yes, this is completely normal, tiancs2008.

svchost.exe , from what I understand, carries out a bunch of services and stuff together as one process. (Like the wireless capabilities + indexing + many others.)

Now, even though that is a common Windows process, you probably have caught something that imitates the process name (so people wouldn't normally terminate it since svchost.exe is usually for important Windows functionality).

Check out this page, a svchost.exe caused by a virus: http://www.processlibrary.com/directory/?files=scvhost.exe .

Here is a Wikipedia page, http://en.wikipedia.org/wiki/Svchost , on it, which better explains your situation. Also, a more complete list of services that use the svchost.exe process (by CastleCops) http://castlecops.com/modules.php?name=O23&query=svchost.exe .

Unfortunately, that's as far as I can help. Without more information, I don't know whether you caught a virus, false positive, ectera. Post back with more information, and perhaps some logfiles !!

Nothing unusual in your Task Manager, see image of mine

Many trojans/malware use the names of system files (but located in a different location to the system files) to confuse the user into believing they are system files, the give away is they aren't in the windows system(32)/s folders.
