AdblockPlus32.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AdblockPlus32.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 AdblockPlus32.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 AdblockPlus32.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 AdblockPlus32.dll errors include:
- Access Violation at address - AdblockPlus32.dll.
- AdblockPlus32.dll could not be found.
- Cannot find C:\Program Files\Adblock Plus for IE\AdblockPlus32.dll.
- Cannot register AdblockPlus32.dll.
- Cannot start Adblock Plus for Internet Explorer. A required component is missing: AdblockPlus32.dll. Please install Adblock Plus for Internet Explorer again.
- Failed to load AdblockPlus32.dll.
- The application has failed to start because AdblockPlus32.dll was not found.
- The file AdblockPlus32.dll is missing or corrupt.
- This application failed to start because AdblockPlus32.dll was not found. Re-installing the application may fix this problem.
Your AdblockPlus32.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, AdblockPlus32.dll file corruption could be caused from a power outage when loading Adblock Plus for Internet Explorer, system crash while loading AdblockPlus32.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.
