Reboot Windows XP after repair

Hello everyone
Let me explain my problem from the beginning: that all began when I do an analysis of virus avast, he found a Trojan in the svchost.exe which he then deleted (I was not in front of my computer time of the analysis). Since this file supports almost all processes of windows so I fix it.

I'm already going into the console with cd windows for a repair manual entering these lines: chkdsk / r and fixboot. That has not changed and I spent automated repair included with the CD, all goes well it resets windows (installation of 30 minutes with the devices etc.) and then when loading windows (after reboot ) It restarts! There is not even the start screen reboot the PC that already ....
Here I have a bit of computer skills but now I'm dry!

please help

You've done a chkdsk and fixboot but have you returned the file svchost.exe?

If not then:
You should have another here:
C: \ WINDOWS \ ServicePackFiles \ i386
c:\windows\system32 Via copy the console in c: \ windows \ system32

hank you command that I have used is well / COPY ?

Yes it is ....

Code
copy C: \ WINDOWS \ ServicePackFiles \ i386 \ svchost.exe C: \ Windows \ system32

small problem I met "The file specified". Is it possible to reconstruct the file or files to recharge the basic system32?

We must get it from another PC (it dates from April 2008) and approximately 14ko

It can also be:
C: \ WINDOWS \ $ NtServicePackUninstall $
or
c:\I386

ok, I put a svchost.exe in my USB key, the problem is that it does not detect the directory / system32.
When I type this command line, copy D: / svchost.exe C: / windows it makes me that the file has been pasted but as soon as I add / system32 I met that no has not found the system32! I understand nothing at all that ..... I think I have to reinstall my 350 GB of data (for a file 14kb ....

What can I do?

Normally after a boot via the console you fall in the c: \ windows.
If you type:
cd system32 then entry.
get yourself in the c: \ windows \ system32 ?

If it does not is that altogether your system32 directory that has disappeared, but I am surprised many.
the syntax of the copy is made with backslash \ and not slash (UNIX)
