RatingDllhost executes dll's. It is not malicious by itself - it is the dll's it hosts that are the problem. If it is hosting a malicious dll then it is malicious. Donovan

Ratingdllhost.exe provides the necessary hooks to allow existing COM DLLs to behave as a local (or remote) server by wrapping them into a surrogate process. The dllhost.exe utility will load COM-based DLLs and expose their functionality from a distinct process, leaving the COM servers code base unaltered (no need to change and recompile the source code). I used it for some software projects. Michael
