What are iaucore.dll Error Messages?


Dynamic Link Library iaucore.dll Errors

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

Your iaucore.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Trend Micro Antivirus Plus Security), or deleted by a malware infection. Furthermore, iaucore.dll file corruption could be caused from a power outage when loading Trend Micro Antivirus Plus Security, system crash while loading iaucore.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.
