What might not seem hard may not be the case, e.g. there are three bars in the small icon try squeezing 5 stars into that Icon and it won't be so small.
Not to mention Malicious if know would be blocked by the network and or web shields. There is currently no interface between the virus labs data and the web rep, that at some point will happen. But as far as I'm aware as an avast user not employee, is the three bar multi colour side of it would stay. So 3x3 gives nine options/possible levels of classification.
