W32/Autorun-BD is a worm for the Windows platform.
When first run W32/Autorun-BD copies itself to:
<Windows>\java\svch0st.exe
<Windows>\pchealth\dllh0st.exe
<Root>\autorun.exe
and creates the file <Root>\autorun.inf
W32/Autorun-BD also copies itself to all removable devices as autorun.exe and creates the file autorun.inf to execute itself when the removable device is connected to another computer.
