What are avfilter-5.dll Error Messages?

Dynamic Link Library avfilter-5.dll Errors

avfilter-5.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like avfilter-5.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. CMS) could share the same avfilter-5.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 avfilter-5.dll is attempted to be loaded either when CMS is starting up, or in some cases already running. Some of the most common avfilter-5.dll errors include:

• Access Violation at address - avfilter-5.dll.
• avfilter-5.dll could not be found.
• Cannot find C:\Program Files (x86)\NovoSun Technology Limited\Security Camera Suite\CMS\avfilter-5.dll.
• Cannot register avfilter-5.dll.
• Cannot start CMS. A required component is missing: avfilter-5.dll. Please install CMS again.
• Failed to load avfilter-5.dll.
• The application has failed to start because avfilter-5.dll was not found.
• The file avfilter-5.dll is missing or corrupt.
• This application failed to start because avfilter-5.dll was not found. Re-installing the application may fix this problem.

Your avfilter-5.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with CMS), or deleted by a malware infection. Furthermore, avfilter-5.dll file corruption could be caused from a power outage when loading CMS, system crash while loading avfilter-5.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.
