What are cmdguard.sys Error Messages?


cmdguard.sys Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with cmdguard.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of cmdguard.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. Comodo Antivirus update) issues. Some of these errors include:

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: cmdguard.sys.

<strong>STOP 0x0000001E: KMODE EXCEPTION NOT HANDLED (cmdguard.sys)</strong><br /><strong>STOP 0x0000007E: SYSTEM THREAD EXCEPTION NOT HANDLED (cmdguard.sys)</strong><br /><strong>STOP 0x0000000A: IRQL NOT LESS EQUAL (cmdguard.sys)</strong><br /><strong>STOP 0×0000007A: KERNEL DATA INPAGE (cmdguard.sys)</strong><br /><strong>STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (cmdguard.sys)</strong><br /><strong>STOP 0x0000003B: SYSTEM SERVICE EXCEPTION (cmdguard.sys)</strong>

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter cmdguard.sys BSOD errors after you've installed new hardware, software (Comodo Antivirus), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to cmdguard.sys Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.


GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a cmdguard.sys Blue Screen of Death error after recent changes.



How to Fix cmdguard.sys 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 cmdguard.sys 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.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the cmdguard.sys error, please proceed to the Step 2 below.

Step 2: If recently installed Comodo Antivirus (or related software), uninstall then try reinstalling Comodo Antivirus software.

You can uninstall Comodo Antivirus software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".
  3. In the search results, find and click "Add or Remove Programs"
  4. Find the entry for Comodo Antivirus 12.0.0.6914 and click "Uninstall"

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many cmdguard.sys error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  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 cmdguard.sys error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

  4. Restart your computer.

Download cmdguard.sys Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying cmdguard.sys to your appropriate Windows system directory. Comodo Group typically does not release Comodo Antivirus SYS 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 cmdguard.sys and all other SYS files for Comodo Antivirus. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
