Scvhost.exe

[Don]

Can someone tell me what this is? It keeps coming up only
when I get calls on my modem. When it does it locks the
modem up and I have to reboot to get it to work again.
I am using Windows 2000

Service Host is a program that allows DLLs and other components to run as NT
services.
An NT service is usually an EXE with certain characteristics, which
diffirentiate from a
normal app, but in some cases it is necessary to "run" a DLL or some other
type of
component as a service. This is where svchost cmes in. It provides the
necessary
"wrapper" so that these components can run as services.

When Win reports that svchost has failed, what it is saying is that the
component that
is running as a service has failed or shut down or commited suicide. In some
cases,
svchost hosts more than one service.

To see what svchosts you have, do a Ctrl Alt Del, Task Manager and then
Processes.
Don't be surprised if you find more than one.

svchost has gotten much attention lately because if you are frequently
getting an error in
this file, it could mean that your PC is infected by some virus.

I am having a problem with that file as well, someone
mentioned it may be virus related, because it's almost
always running, and at 99% processor utilization. From
what I found, it runs all the services (dll's etc). I
found this somewhat helpful:

My AV software should have caught anything, but I just
dl'd the latest signatures and am manually scanning right
now... hope this helps.

It just dawned on me.. did you misspell svchost?
You say scvhost in your title.

I ask becasue I found this:

Note that one of the files that contain this worm
is scvhost.exe. The Win OS name is svchost, not scvhost.

A friend of mine had an attack from an SVCHost type
Trojan. It came from a screen saver. It actually
replaced svchost.exe. The size of the Trojan was 21.6 KB
(22,212 bytes)- size on disk was 32.0 KB (32,768 bytes).
That was for windows 2000. Normally svchost.exe for
win2000 is about 7.76 KB (7,952 bytes) The fix is fairly
easy. You need to replace the Trojan with a legitimate
copy. If this is your problem and you have a firewall,
you should see it trying to call back home.
