checkered red/white bar in Comodo icon

At times, my Comodo CIS icon in my system tray shows a red corner. At times, a red and white checkered pattern is briefly over its left half. I guess the Comodo docs explain all this, but I cannot find it. What do these things mean?

Do you mean the red arrows which go downwards on the shield icon?
You should also get green ones going upwards on the right side.

If so it is red for data coming in(downloading) green for data being sent(uploaded)
