Can anyone out there PLEASE help me.

My desktop was recently hijacked. I ran Hijack this and housecall, AdAware, Spybot, and Spykiller. I read an earlier thread about this same problem, but I still can't get my desktop back.

My browser is fine, but my desktop had a permanent background saying "Warning, you're in danger" My housecall scan shows two infected files, but I can't clean or delete them.

The two files are (windows\system32\svc.exe)
and (Windows\system32.child.dl)

I am not real computer literrate, so anyone that can walk me through this would be my new Hero.

Thanks
