AdblockPlus64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AdblockPlus64.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. Adblock Plus for Internet Explorer) could share the same AdblockPlus64.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 AdblockPlus64.dll is attempted to be loaded either when Adblock Plus for Internet Explorer is starting up, or in some cases already running. Some of the most common AdblockPlus64.dll errors include:
- Access Violation at address - AdblockPlus64.dll.
- AdblockPlus64.dll could not be found.
- Cannot find C:\Program Files\Adblock Plus for IE\AdblockPlus64.dll.
- Cannot register AdblockPlus64.dll.
- Cannot start Adblock Plus for Internet Explorer. A required component is missing: AdblockPlus64.dll. Please install Adblock Plus for Internet Explorer again.
- Failed to load AdblockPlus64.dll.
- The application has failed to start because AdblockPlus64.dll was not found.
- The file AdblockPlus64.dll is missing or corrupt.
- This application failed to start because AdblockPlus64.dll was not found. Re-installing the application may fix this problem.
Your AdblockPlus64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adblock Plus for Internet Explorer), or deleted by a malware infection. Furthermore, AdblockPlus64.dll file corruption could be caused from a power outage when loading Adblock Plus for Internet Explorer, system crash while loading AdblockPlus64.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.
