Comodo Security Agent could not be started...

Everytime I start my pc I get this error: “Comodo Security Agent could not be started.
Would you like to run diagnostics tool to fix this error?”

This problem has existed some time already and Diagnostics tool found no errors until today. It said it found some errors it can’t fix automatically…

I have recently uninstalled and then re-installed Comodo Firewall but it did not help. I’ll attach the latest log file.

Help please?

I have the same problem. Is there any solution?

Hi Juhaaa,

  1. Did you install avast! recently?
  2. What modules do you have enabled?


Yeah, about three weeks ago. I have all modules enabled. Could that be somehow the troublemaker?

Not necessarily but it could interfere on certain configurations. Do you have another firewall enabled (e.g. avast!) ?


No, I only have Avast Antivirus and I don’t use other firewalls.

Go to %SystemRoot%\system32\drivers
Delete inspect.sys
Restart computer system
Run “Diagnostics” tool

All right, here is new report.

  1. Go to Control Panel\Network and Internet\Network Connections
    Right-click on your network connection > Select “Properties” > Uninstall “COMODO Internet Security Firewall Driver”
    Restart computer system
    Run “Diagnostics” tool

  2. Try to uninstall avast!.

  3. Try to re-install using this guide.

  4. Update NetworkCard driver.


Hello again,

I did step 1. but when I clicked restart-button, I had Bluescreen. Then I did other steps (my drivers are up-to-date already) but I still have the same issue. Currently, Avast is not installed anymore so apparently it’s not the one to blame.

Latest report also included.

Sorry to hear that. Please create a bug report with the required format.

Thank you.

Okay, I guess I’ll then do a bug report. But thank you anyway for helping.
