I found winsupdater.exe in the taskmanager,and it automatically  execute  in
the startup.When i  disabled it in the startup option,but i still
automatically execute.Even I can not install the anti-adware .How can i fix
it?I search it in Google,and nothing is valuable.And the computer is very
slow.
Any suggestion is appreciated.

Its a variant of this virus/worm :

I would remove these keys and delete the file........ it supposedly deletes
a real windows file
during install, yet I do not know which one.................. a lot of these
can recreate themselves
which makes them nasty totally remove..................

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\]
MicroSoft Window Updater=winsupdater.exe

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\]
MicroSoft Window Updater=winsupdater.exe

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\]
MicroSoft Window Updater=winsupdater.exe
