So my roommate's laptop has recently been infected by the ldcore.dll trojan.

I've tried removing it from the registry, deleting it through command prompt, deleting with KillBox, and deleting it with HijackThis. Each time I get an error saying I am unable to delete the file.

The HJT log is below, thanks in advance:
