dllhost.exe and omxosua.exe keeps coming back... please help

Hi, My name is Moon.
As I described above, i have same problem with others or worse.

It started with multiple dllhost.exe but now is showing omxosua.exe as well.
Both of them are popping up without permission and even if i shut them down in task manager,.
It keeps coming back slowing my computer down.

I think I even see ubatt.exe which i dont even know what it is.
It doesnt slow me down but even if i shut that off in task manager, it keeps coming back.

Please help me to remove this virus...
