What are application_categorizer.dll Error Messages?


Dynamic Link Library application_categorizer.dll Errors

application_categorizer.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like application_categorizer.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 application_categorizer.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 application_categorizer.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 application_categorizer.dll errors include:

Your application_categorizer.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, application_categorizer.dll file corruption could be caused from a power outage when loading ZoneAlarm Pro Antivirus+Firewall 2019, system crash while loading application_categorizer.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.



How to Fix application_categorizer.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your application_categorizer.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.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the application_categorizer.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
