BSOD due Commodo?

Various BSOD at random times. I don’t see any pattern except that Commodo shows up frequently in BlueScreenView.

I’m stumped.

Win7 Pro 32-bit
Commodo Free Firewall 7.0.317799.4142

Hi coyote2,

Are you also running Avast! Free Antivirus? I am running both of these programs and also have a history of BSODs with WhoCrashed and windbg indicating Comodo (cmdguard.sys) in their results. Please see the topic I started on this issue: Conflict between Comodo Free Firewall and Avast! Free Antivirus ( ) for more information.

Please let me know if I can be of any help.

Best regards,


You are running an old version of CFW.

Hi mybuddy1998,
I’m not using Avast, I’m using Norton AntiVirus.
