Protect4a647d98.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Protect4a647d98.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 RAR File Opener) could share the same Protect4a647d98.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. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when Protect4a647d98.dll is attempted to be loaded either when Free RAR File Opener is starting up, or in some cases already running. Some of the most common Protect4a647d98.dll errors include:
- Access Violation at address - Protect4a647d98.dll.
