Security products are supposed to prevent system failures and malfunctions caused by viruses and other malware. Every so often, however, a security product stops making the user's life easier and adds to his grief instead. If you use the Comodo Personal Firewall, you may be experiencing such grief in the form of randomly occurring Blue Screens of Death (BSODs). There is no one way to fix this, but there are several ideas you should try.

Things you need
- Account with administrative privileges
- Identity of network adaptors
- Network adaptor driver installation files
- Comodo Internet Security installation file
Identify your network adaptors. Click the "Start" button. Right-click "Computer" and select "Manage." Select "Device Manager" from the left pane of the Computer Management window. Select and expand "Network adapters" from the right pane. For each adaptor, right-click the adaptor name, select "Properties" and click the "Driver" tab. Note the "Driver Provider," "Driver Date" and "Driver Version." Click "Cancel" to exit Properties. Click the "Close" button to exit Computer Management when finished.
Obtain and install updated network adaptor drivers from Microsoft Update or the driver providers' websites. Reboot after completing the updates. If the Blue Screens of Death persist, open Windows Explorer and locate the inspect.sys file. Delete the inspect.sys file and reboot. Your Comodo product will generate a new inspect.sys file. If the Blue Screens of Death persist, proceed to Step 3.
Update your Comodo product. This issue was associated with versions 2.x of the Comodo Personal Firewall; users who upgraded to version 3 of the product reported no recurrences. Download the appropriate product for your operating system, install and reboot. If the Blue Screens of Death persist, delete the inspect.sys file and reboot. If the issue persists, proceed to Step 4.
Replace your network adaptors. Start with the one used most frequently; replace the others if issues persist. Use "name" brands; many Blue Screen of Death incidents have been traced to conflicts with "budget" network adaptor drivers. Install the most current driver for your new adaptor. If the Blue Screens of Death persist, or if you cannot replace integrated adaptors with external adaptors, proceed to Step 5.
Replace your motherboard and drivers, using a screwdriver to access them. Network adaptors, be they internal or external, should be "name" brands. If the Blue Screens of Death persist, record their contents and contact Comodo Technical Support, attaching the data from the Blue Screen of Death as well as your system configuration and most recent memory dump.
Tips and warnings
- Follow this procedure if your Blue Screens of Death are associated with upgrading to Windows 7. Download and run the Windows 7 Upgrade Advisor (see Resources) to assess your Comodo product's compatibility. Uninstall your Comodo software, then upgrade Windows. Download and install the appropriate Comodo product.
- The 32-bit versions of security software do not work in 64-bit versions of Windows and vice versa. Determine if your Windows installation is 32-bit or 64-bit before upgrading your Comodo software.
