Warn them that they need to look for prechecked check boxes or implied acceptance of unrequested software downloads. Warn them that the site has misleading buttons. Warn them that the page may redirect them to some other site or open other sites in new but in the background windows. Warn them that site has hidden hotspots or even page wide invisible hotspots. Warn them that the site will try to stop them from leaving the page once they have entered it. Warn them of anything undesirable the site may be doing whether it it is doing it legally or not. Give users the option to permanently block such sites.
Norton does block and warn about known malicious and phishing sites, as well as sites that pose ecommerce safety threats. What you have described, however, are issues that can happen at any website you visit, even the ones that are usually considered "safe." Therefore, what you are asking to be warned about are things that anyone surfing the web should already be taking steps to mitigate as a matter of course. I am not defending some of the deceptive practices that some bundled software uses, but I am suggesting that nearly all of the dire consequences can be avoided if a user simply pays attention and reads what the installation screens are telling them.
That being said, there is a list of "unwanted add-on software" maintained by Calendar of Updates that you can use. The first thing you will notice is that Google and Yahoo! do a lot of piggybacking. As Quads mentioned, most of this stuff involves high-profile, legitimate companies, and I really don't see how a security company could possibly start blocking these things without running into accusations of trade interference. The user, on the other hand, always has a choice about accepting an offer or rejecting it.
