Getting Around Browser Warnings about Bad Sites

What's an attacker to do when faced with his/her malicious site being displayed as 'bad site' by a web browser like IE7?

It just goes to show that attackers will always take the path of least resistance.

Why bother trying to keep under the radar of webpage filters when you can craft malware that adds an extra layer of 'convincing information' to the user's browser?

I thought this was a very clever way to get around these types of web filter-based protection mechanisms. Obviously, our honeyclients would still identify these sites as being 'bad', since we're not relying on user judgment.
