Fix and Remove RUNDLL: backgroundcontainer.dll

RunDLL is a Windows file that loads all the .dll modules on your system (dll stands for Dynamic Link Library) and is a legitimate file, however it can also load malware related files. The error normally occurs when the dll file was set to run at startup or as a task at a later time and the module itself has been removed already by your Anti-Virus or Anti-Malware software. However the registry entry telling Windows to load the file is still left, since Windows fails to load the file (since its been deleted already).
