General Firewall.mof Runtime Errors

Firewall.mof file errors often occur during the startup phase of Windows, but can also occur while the program is running. These types MOF errors are also known as “runtime errors” because they occur while Windows is running. Here are some of the most common Firewall.mof runtime errors:

Most MOF errors are due to missing or corrupt files. Your Firewall.mof file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows), or deleted by a malware infection. Furthermore, Firewall.mof file corruption could be caused from a power outage when loading Windows, system crash while loading or saving Firewall.mof, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.

CAUTION : We strongly advise against downloading and copying Firewall.mof to your appropriate Windows system directory. Microsoft typically does not release Windows MOF files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing Firewall.mof and all other MOF files for Windows. An incorrectly installed MOF file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
