libclamunrar.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libclamunrar.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like ClamTray.exe - to follow. These files were created so that multiple programs (eg. ClamWin) could share the same libclamunrar.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 libclamunrar.dll is attempted to be loaded either when ClamWin is starting up, or in some cases already running. Some of the most common libclamunrar.dll errors include:
- Access Violation at address - libclamunrar.dll.
- libclamunrar.dll could not be found.
- Cannot find C:\Program Files (x86)\ClamWin\bin\libclamunrar.dll.
- Cannot register libclamunrar.dll.
- Cannot start ClamWin. A required component is missing: libclamunrar.dll. Please install ClamWin again.
- Failed to load libclamunrar.dll.
- The application has failed to start because libclamunrar.dll was not found.
- The file libclamunrar.dll is missing or corrupt.
- This application failed to start because libclamunrar.dll was not found. Re-installing the application may fix this problem.
Your libclamunrar.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ClamWin), or deleted by a malware infection. Furthermore, libclamunrar.dll file corruption could be caused from a power outage when loading ClamWin, system crash while loading libclamunrar.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.
