Sorry first as my computer can not start and thus no chinese input system here this computer.
The problem:
When I scanned my computer, I found a trojan: download.trojan which came from Malaysia and could not delete or quarantine or repair.
Thus I found the trojan was in smss.exe under c:/windows/system32.
So I deleted the smss.exe and the its value in the registery
Before deletion, I copy the registery in my computer and the smss.exe also
Now I can not restart my computer, even the sate mode.
Always say: Windows XP interrupted and blue screen with the words:Windows XP met a problem when start. So shut down to protect your computer.
Help me please
Thank you very much
