Libcurl.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libcurl.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Defrag.exe - to follow. These files were created so that multiple programs (eg. BullGuard Internet Security) could share the same libcurl.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 libcurl.dll is attempted to be loaded either when BullGuard Internet Security is starting up, or in some cases already running. Some of the most common libcurl.dll errors include:
- Access Violation at address - libcurl.dll.
- Libcurl.dll could not be found.
- Cannot find C:\ProgramData\BullGuard\Update\Download\APPDIR\libcurl.dll.
- Cannot register libcurl.dll.
- Cannot start BullGuard Internet Security. A required component is missing: libcurl.dll. Please install BullGuard Internet Security again.
- Failed to load libcurl.dll.
- The application has failed to start because libcurl.dll was not found.
- The file libcurl.dll is missing or corrupt.
- This application failed to start because libcurl.dll was not found. Re-installing the application may fix this problem.
Your libcurl.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BullGuard Internet Security), or deleted by a malware infection. Furthermore, libcurl.dll file corruption could be caused from a power outage when loading BullGuard Internet Security, system crash while loading libcurl.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.
