scheduler_loc0405.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like scheduler_loc0405.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. ZoneAlarm Antivirus) could share the same scheduler_loc0405.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 scheduler_loc0405.dll is attempted to be loaded either when ZoneAlarm Antivirus is starting up, or in some cases already running. Some of the most common scheduler_loc0405.dll errors include:
- Access Violation at address - scheduler_loc0405.dll.
- scheduler_loc0405.dll could not be found.
- Cannot find C:\Program Files (x86)\CheckPoint\ZoneAlarm\scheduler_loc0405.dll.
- Cannot register scheduler_loc0405.dll.
- Cannot start ZoneAlarm Antivirus. A required component is missing: scheduler_loc0405.dll. Please install ZoneAlarm Antivirus again.
- Failed to load scheduler_loc0405.dll.
- The application has failed to start because scheduler_loc0405.dll was not found.
- The file scheduler_loc0405.dll is missing or corrupt.
- This application failed to start because scheduler_loc0405.dll was not found. Re-installing the application may fix this problem.
Your scheduler_loc0405.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ZoneAlarm Antivirus), or deleted by a malware infection. Furthermore, scheduler_loc0405.dll file corruption could be caused from a power outage when loading ZoneAlarm Antivirus, system crash while loading scheduler_loc0405.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.
