Windows Security Alerts

As a newcomer of uncertain age, but well beyond anyone’s definition of CHILD category, I’m curious as to its appearance at top of each Forum topic?

My problem is the “Not Found” box which causes warning icon on lower task bar (red shield with X).
How do I get Comodo recognized in order to have the warning removed?

I am on Vista Ultimate and IE7.

Appreciate help in this strange problem.

Are you using Vista with admin rights or as limited user?

Can you tell us what Comodo’s system status is. Look in the main screen under Summary → System Status. If there is a fault reported run Diagnostics (under Miscellaneous) and see if that does the trick or not.
