kcleaner.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like kcleaner.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. Clean Master for PC) could share the same kcleaner.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 kcleaner.dll is attempted to be loaded either when Clean Master for PC is starting up, or in some cases already running. Some of the most common kcleaner.dll errors include:
- Access Violation at address - kcleaner.dll.
- kcleaner.dll could not be found.
- Cannot find C:\Program Files (x86)\cmcm\Clean Master\kcleaner.dll.
- Cannot register kcleaner.dll.
- Cannot start Clean Master for PC. A required component is missing: kcleaner.dll. Please install Clean Master for PC again.
- Failed to load kcleaner.dll.
- The application has failed to start because kcleaner.dll was not found.
- The file kcleaner.dll is missing or corrupt.
- This application failed to start because kcleaner.dll was not found. Re-installing the application may fix this problem.
Your kcleaner.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Clean Master for PC), or deleted by a malware infection. Furthermore, kcleaner.dll file corruption could be caused from a power outage when loading Clean Master for PC, system crash while loading kcleaner.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
