o_raydream.dll is a module DLL file. Module DLL files are files that only contain a section of code that executes a task or operation. DLL files are commonly used by more than one application or program thus allowing your computer to do more while using less space.
Useless DLL files are sometimes the result of improperly installed or incomplete deletion of programs. They are not used by any programs on your computer and therefore pile up in a mess that slows down all programs and applications. Other DLL files are malicious and have come into your computer via the internet or your email.
These can wreak havoc on your system or quietly steal your information. Either way, it is time to clean your system’s registry. Go to ZookaWare PC Cleaner and let them scan your computer free. They will eliminate useless files and errors from your system and have your computer running like new.
