120_1.0_VideoConverterUltimate_plug.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like 120_1.0_VideoConverterUltimate_plug.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Free FLV to MP4 Converter) could share the same 120_1.0_VideoConverterUltimate_plug.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems.
