1. The icon top left in the browser tab, is the one associated with and supplied by the website you are visiting.

  2. The one top right is the one for the Avast Online Security (browser add-on), it relates to the ranking for the page/tab that you have open (Green Good) and if there is any tracking on that page.

  3. The bottom right of the screen is the avast tray icon it should be coloured as per your image. When avast is scanning something then it rotates, it doesn’t have any numbers associated with that, but it can also give indications on your security state. e.g. one or more Shields stopped/disabled/not running. These indications could be a Red circle with a white X over the tray icon, avast isn’t running; a Yellow triangle with an ! (exclamation mark) over the tray icon, one or more shields stopped or disabled, etc.

This one really shouldn’t have any numbers on it, so we need to see a screenshot if you can replicate it.
