Svchost in Windows Xp

I have installed Windows XP with service pack 1 on a computer, and before connecting it to the itnernet i made all the updates possible to the anti virus and installed all the hotfixes not included in the service pack ( including the blaster fix ).
But shortly after the install, svchost is constantly putting the cpu in max charge.

How can i fix this?

4660 » What is the Svchost.exe process(es) in Windows XP?

In tip 2060, I explained the Svchost process in Windows 2000.

In tip 4310, you can see multiple Svchost processes in Windows XP.

%SystemRoot%\System32\Svchost.exe is a generic process name for services that run from dynamic-link libraries (DLLs). When you start Windows XP, Svchost,exe constructs multiple lists of service groupings that need to be loaded. Each instance can run at the same time. Svchost,exe groups are delineated at:

HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Svchost.

Each Value Name contains a list of included serviceDLL values, in a REG_MULTI_SZ data type. These servies are extracted from HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\<Service Short Name>.

To see the list of active services in each process, open a CMD prompt and Type:

Tasklist /SVC

The following was displayed from one of my Windows XP Professional computers:

Try disabling unneeded services:
http://www.blackviper.com/WinXP/servicecfg.htm
http://www.techspot.com/tweaks/win2k_services/index.shtml

You can also try the following method to eliminate items from startup:
Click Start->Run->MSCONFIG

In the Startup tab, start out by disabling everything you're unfamiliar with (or everything if you're unsure).
Optionally, you can also disable non-Microsoft services from the Services tab.
If the problem no longer exists after a reboot, then you can narrow it down as one of the items in your
startup. To permanently remove these item(s), proceed as follows...

Click Start->Run->Regedit
*Be careful when editing the registry as an accidental deletion can render your system inoperable.
First navigate to the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
*You might also find RunOnce, RunOnceEx, RunServices, RunServiceOnce or any of these with a trailing dash (-)

Once found, click File, Export to save a copy of the key before you delete any items (if necessary).
After the file has been saved, delete items as needed from the right pane.
Now find the next startup key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
*You might also find RunOnce, RunServices, RunServiceOnce or any of these with a trailing dash (-)
Follow the previous procedures to export a copy before deleting items from the right pane.

You have the Coolwebsearch hijacker I think.
Go to this page http://www.spywareinfo.com/~merijn/downloads.html and download CWshredder
Read that page for further info on that. Say's to run HijackThis afterward's.
Direct Link: http://209.133.47.200/~merijn/files/CWShredder.exe
Get that and run it to remove it.

I checked the running processes and there is nothing abnormal, neither on the registry. I also ran the CWshredder but the problem still remains.

I believe Veegertx got the right awnser, I reinstalled the system and I didn't have the problem again because I still have not placed the original Hosts file with one I have to block ads that is over 1 MB.

Even though I haven't tested it , I'm pretty sure that is it because this was the only PC in the network that was using it.
I noticed it blocked some msft sites, that can explain why it would mess the system when I opened Outlook.

THanks man, sorry for the delay, way too much work.

Thanks and
Glad you enlightened us to this also. I've used those really large HOST files before and I remember problem's but not exactly like you had. Perhap's a firewall may be better with a limited HOST file.
