I am not sure I follow you. By that you mean that CNET installer is a malware because its installing toolbar without disclosing it to the user? Surely StartNow toolbar should not be marked because somebody decides to bundle it. If I take your software and bundle it does it make it malware? I am arguing that all those toolbars do same things, and they should be marked as PUP not as malware as they are not in the same category as viruses.
