What are cf_engines.dll Error Messages?

Dynamic Link Library cf_engines.dll Errors

cf_engines.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like cf_engines.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 Pro Antivirus+Firewall 2019) could share the same cf_engines.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 cf_engines.dll is attempted to be loaded either when ZoneAlarm Pro Antivirus+Firewall 2019 is starting up, or in some cases already running. Some of the most common cf_engines.dll errors include:

Access Violation at address - cf_engines.dll.
cf_engines.dll could not be found.
Cannot find C:\Program Files (x86)\CheckPoint\ZoneAlarm\avsys\cf_engines.dll.
Cannot register cf_engines.dll.
Cannot start ZoneAlarm Pro Antivirus+Firewall 2019. A required component is missing: cf_engines.dll. Please install ZoneAlarm Pro Antivirus+Firewall 2019 again.
Failed to load cf_engines.dll.
The application has failed to start because cf_engines.dll was not found.
The file cf_engines.dll is missing or corrupt.
This application failed to start because cf_engines.dll was not found. Re-installing the application may fix this problem.

Your cf_engines.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ZoneAlarm Pro Antivirus+Firewall 2019), or deleted by a malware infection. Furthermore, cf_engines.dll file corruption could be caused from a power outage when loading ZoneAlarm Pro Antivirus+Firewall 2019, system crash while loading cf_engines.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.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your cf_engines.dll issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

Step 3: Perform a Windows Update.

In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
