my problem is solved,because i use system restore and back to two days ago.
why my HJT's log short,because i always select all the item and fix checked.
and i always run antivirus to remove any virus ,trojan and others.
after that i uninstall it,because i don't want system run too many software.
and my startup item only have one,only msn in my startup item.
anyway i sure this two thing is make me cannot see desktop and do you know how to fix it ?
O4 - HKLM\..\RunOnce: [1sje7rk6lk] %systemroot%\system32\Rundll32.exe %systemroot%\system32\1sje7rk6lk.dll,DllUnregisterServer
O20 - Winlogon Notify: Xtpdriw - D:\WINDOWS\SYSTEM32\Xtpdriw.dll
and here is my latest HJT'log after i run system restored and install Internet explorer 7.
can you tell me which item in my HJT's log can fix checked?
because i don't want system run too many thing and make system slow.
