What are ignis.sys Error Messages?

ignis.sys Blue Screen of Death (BSOD) Errors

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 These types of ignis.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg.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

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (ignis.sys).

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

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter ignis.sys BSOD errors after you've installed new hardware, software (Adaware Antivirus), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to ignis.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 ignis.sys Blue Screen of Death error after recent changes.

How to Fix ignis.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 ignis.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 ignis.sys error, please proceed to the Step 2 below.

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

You can uninstall Adaware 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 Adaware Antivirus 12.4.930.11587 and click "Uninstall"
  5. Follow the prompts for uninstallation.

After the software has been fully uninstalled, restart your PC and reinstall Adaware Antivirus software.

If this Step 2 fails as well, please proceed to the Step 3 below.

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

If Those Steps Fail: Download and Replace Your ignis.sys File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate ignis.sys file version. We maintain a comprehensive database of 100% malware-free ignis.sys files for every applicable version of Adaware Antivirus. Please follow the steps below to download and properly replace you file:

  1. Locate your Windows operating system version in the list of below "Download ignis.sys Files".
  2. Click the appropriate "Download Now" button and download your Windows file version.
  3. Copy this file to the appropriate Adaware Antivirus folder location:
    Windows 10: C:\Windows\System32\drivers\
    Windows 10: C:\Program Files\adaware\adaware antivirus\Firewall Engine\\
  4. Restart your computer.

If this final step has failed and you're still encountering the error, you're only remaining option is to do a clean installation of Windows 10.

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve ignis.sys problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

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

CAUTION : We strongly advise against downloading and copying ignis.sys to your appropriate Windows system directory. Lavasoft typically does not release Adaware 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 ignis.sys and all other SYS files for Adaware 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.
