I've seen that too.
Even with the avast program running properly here, first attempt to view system contents in my avast dot com will always result in some categories in red, even though other pages will show the red categories as active and green with a green checkmark.
A second attempt to view the same infograph will always report the correct status. To do that, close the current window showing the erroneous infographic and then immediately re-open the same system information graph. You will see all categories are now green.
As this site is still beta, I assume some bugs have yet to be fixed.
There is also the fact that you are talking to an avast server and sometimes it takes some time for your system information to be updated.
Most of the time it is only a second or two for this to happen but often just updating the avast program manually via virus updates will clear your issues. The final part of the update is sending off your system statistics to the avast server. Information contained in statistics sent will update your my avast dot com page as soon as your avast program completes the update and you should see new information on your my avast page.
You'll likely need to refresh your my avast page to see the newest information.
