Sounds like this <http://www.sophos.com/virusinfo/analyses/trojcoreflooc.html> might be your problem. If you're using NTFS it adds itself as an ADS to \system32 and explorer.exe which is why you can't find the files.

You may be able to get rid of it by using a command like

        rundll32 c:\winnt\system32:acbdhpd.dll,Uninstall
