Plugin_Facebook.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like Plugin_Facebook.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. Baidu WiFi Hotspot) could share the same Plugin_Facebook.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 Plugin_Facebook.dll is attempted to be loaded either when Baidu WiFi Hotspot is starting up, or in some cases already running. Some of the most common Plugin_Facebook.dll errors include:
- Access Violation at address - Plugin_Facebook.dll.
- Plugin_Facebook.dll could not be found.
- Cannot find C:\Program Files (x86)\Baidu WiFiHotspot\Plugins\Plugin.Facebook\Plugin_Facebook.dll.
- Cannot register Plugin_Facebook.dll.
- Cannot start Baidu WiFi Hotspot. A required component is missing: Plugin_Facebook.dll. Please install Baidu WiFi Hotspot again.
- Failed to load Plugin_Facebook.dll.
- The application has failed to start because Plugin_Facebook.dll was not found.
- The file Plugin_Facebook.dll is missing or corrupt.
- This application failed to start because Plugin_Facebook.dll was not found. Re-installing the application may fix this problem.
Your Plugin_Facebook.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Baidu WiFi Hotspot), or deleted by a malware infection. Furthermore, Plugin_Facebook.dll file corruption could be caused from a power outage when loading Baidu WiFi Hotspot, system crash while loading Plugin_Facebook.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.
