re xp locks up

[unionman]

I have discovered that svchost is using 100% cpu while I am on the net
and that is why the machine is locking, so what is svchost? and how can I sort the problem?

From www.liutilities.com:

svchost - svchost.exe - Process Information
Process File: svchost or svchost.exe
Process Name: Microsoft Service Host Process

Description:
svchost.exe is a system process belonging to the Microsoft Windows Operating System which handles processes executed from DLLs. This program is important for the stable and secure running of your computer and should not be terminated.

Note: svchost.exe is also a process which is registered as the Trojan.W32.Dasher. It takes advantage of the Windows LSASS vulnerability, which creates a buffer overflow and instigates your computer to shut down. To see more information about this vulnerability please look at the following Microsoft bulletin: http://www.microsoft.com/technet/security/bulletin/ms04-011.mspx

This is a registered security risk and should be removed immediately.

Determining whether this process is a virus or a Windows process depends on the directory location it executes or runs from in WinTasks.
