Well, he suggested just that and I agree with him. For Web Shield blocked threats, Notifications shouldn't say "Open Virus Chest" because that doesn't make any sense. Web Shield blocked threats are just blocked, there is no entry in the Virus Chest afterwards. For Web Shield based malware detections, there should just be an URL show and no "Open Virus Chest" button.
Like so (see attachment)...
Thx for the idea. I've seen this before during beta test and forgot to report it. I'll forward this to avast! team.
