RunDLL is a legitimate Windows file that executes/loads .dll (Dynamic Link Library) modules which too can be legitimate or sometimes malware related. A RunDLL "Error loading... message usually occurs when the .dll file(s) that was set to run at startup in
the registry has been deleted. Windows is trying to load this file(s) but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry still remains and is telling Windows
to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.
