Another Tray Icon question

Comodo Internet Security - CIS Firewall Help - CIS

Today for the first time I’m seeing the Comodo icon on the system tray with a a round red circle with a line through it (a “don’t” sign). What does it mean?

TIA for any help,

Kathy

It means CIS is not working. Do a search for “red circle” here in the forums and check if some of the results applies to your situation.

Thanks for the suggestion.

Closed it and restarted it, and that fixed it. At least for now.
