Smv64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like smv64.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 smv64.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 smv64.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 smv64.dll errors include:
- Access Violation at address - smv64.dll.
- Smv64.dll could not be found.
- Cannot find C:\Program Files\Trend Micro\AMSP\module\10016\6.5.1143\2.0.1002\smv64.dll.
- Cannot register smv64.dll.
- Cannot start Trend Micro Antivirus Plus Security. A required component is missing: smv64.dll. Please install Trend Micro Antivirus Plus Security again.
- Failed to load smv64.dll.
- The application has failed to start because smv64.dll was not found.
- The file smv64.dll is missing or corrupt.
- This application failed to start because smv64.dll was not found. Re-installing the application may fix this problem.
Your smv64.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, smv64.dll file corruption could be caused from a power outage when loading Trend Micro Antivirus Plus Security, system crash while loading smv64.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.
