nssutil3.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like nssutil3.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like cdriphelper.exe - to follow. These files were created so that multiple programs (eg. Songbird) could share the same nssutil3.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 nssutil3.dll is attempted to be loaded either when Songbird is starting up, or in some cases already running. Some of the most common nssutil3.dll errors include:
- Access Violation at address - nssutil3.dll.
- nssutil3.dll could not be found.
- Cannot find C:\Program Files (x86)\Songbird\xulrunner\nssutil3.dll.
- Cannot register nssutil3.dll.
- Cannot start Songbird. A required component is missing: nssutil3.dll. Please install Songbird again.
- Failed to load nssutil3.dll.
- The application has failed to start because nssutil3.dll was not found.
- The file nssutil3.dll is missing or corrupt.
- This application failed to start because nssutil3.dll was not found. Re-installing the application may fix this problem.
Your nssutil3.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Songbird), or deleted by a malware infection. Furthermore, nssutil3.dll file corruption could be caused from a power outage when loading Songbird, system crash while loading nssutil3.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.
