I don't wish to start a firestorm here--I mean this to be constructive and helpful, not to start an argument--but there are numerous other exploits, mostly running through Javascript, besides viruses. "Fraudulent Website" won't protect you against those. It may be true that Macs are far less vulnerable to these, and most aren't even directed at them, but some are platform independent. Macs aren't bullet proof.
And, there are plenty of sites, without being "fraudulent"--they won't make it onto Google's fraudulent list--that have either been hacked directly or indirectly (unintentionally, possibly through an advertising script, or XSS, Cross Site Scripting), or are directly intent on delivering a dirty payload of one kind or another. And, like a Trojan, or other similar malware, you don't get to make a decision to "Install" or not. There's so much more to this.
Firefox is the only browser--with the Add-On NoScript--I'm aware of that supports protection against these JS exploits.
It seems to me that even if there's only a small chance of picking something up, one would choose to take the path that would reduce that risk. I would love to see Apple offer some sort of Javascript protection with Safari.
And Site Advisor, or anything similar (like WOT), while far from perfect, can warn you about possible threats where Fraudulent Website probably won't.
