I was having the same problem when i installed XP connected to internet.
Seems that when XP looks for upgrades files for instalation got a nice
virus.
Solution: Install XP unplugged. After instalation ends, set up internet
connection with security server and the get windows update files. Also
install som antivirus software.

Charlie,

Svchost.exe is a general purpose process that Microsoft provides to run various
services (background tasks) that let you use the various features of Windows.
If one of the services is running heavily, you will see svchost.exe using a lot
of resources (CPU and memory).

If you want to know more about the many processes running on your computer, get
Process Explorer (free) from
<http://www.sysinternals.com/ntw2k/freeware/procexp.shtml>. Provides way more
information than Task Manager. You can look at any process and see what modules
it contains, and who wrote or distributed each module. For instances of
svchost.exe, you can see what services each provides.

For a good reference to the many system services, see
<http://www.blackviper.com/WinXP/servicecfg.htm>. For discussion about most
processes in general (what is each one, what does it do, is it necessary), just
type it in to your favorite search engine. Anything dangerous is probably being
discussed somewhere on the web.

Cheers,
Chuck

Charlie,

A Google search for "svchos1.exe", OTOH, appears to link THAT process to the
W32/Gaobot worm.
http://groups.google.com/groups?q=svchos1.exe&ie=UTF-8&oe=UTF-8&hl=en&btnG=Google+Search

For removal of Gaobot, Symantec has developed various removal tools. The tool
required may depend upon what version of Gaobot has infected your computer.
http://search.symantec.com/custom/us/query.html then type "gaobot" into the
Search: box.

How current is your virus protection? Try these free online virus scans:
<http://www.bitdefender.com/scan/license.php>
<http://security.symantec.com/ssc/home.asp>
<http://housecall.trendmicro.com/housecall/start_corp.asp>

Now check for, and learn to defend against, additional carriers of infection.

First, download LSP-Fix from <http://www.cexx.org/lspfix.htm>, and CWShredder
from <http://www.majorgeeks.com/download4086.html>. Both free.

Next, run CWShredder. Have it fix all variants.

Now check for, and remove, spyware. Get HijackThis
<http://www.majorgeeks.com/download.php?det=3155> and Spybot S&D
<http://security.kolla.de/index.php?lang=en&page=download>. Both free.
1) Install and run Spybot. First update it ("Search for updates"), then run a
scan ("Check for problems"). Trust Spybot, and make all recommended deletions.
2) Install and run HijackThis. Do NOT make any changes immediately. Save the
HJT Log.
3) Have your HJT log interpreted by experts at one or more of the following
forums (and post it here):
<http://forums.net-integration.net/>
<http://www.spywareinfo.com/forums/>
<http://forums.tomcoyote.org/>
<http://www.wilderssecurity.com/>

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix.

Harden your browser. There are various websites which will check for
vulnerabilities, here are three which I use.
http://www.jasons-toolbox.com/BrowserSecurity/
http://bcheck.scanit.be/bcheck/
https://testzone.secunia.com/browser_checker/

Harden your operating system. Check at least monthly.
http://windowsupdate.microsoft.com/

Block possibly dangerous websites with a Hosts file. Three Hosts file sources I
use:
http://www.accs-net.com/hosts/get_hosts.html
http://www.mvps.org/winhelp2002/hosts.htm
(The third is included, and updated, with Spybot (see above)).

I'm having the same problem with the svchost thing.
whatever you do don't delete the process or your whole
computer will screw up. Please tell me if you get the
problem fixed.
