I found this over the weekend....

Spyware, Adware, Spam, Phishing, Viruses, Identity Theft Protection | SiteAdvisor
SiteAdvisor helps protect you from all kinds of Web-based security threats including spyware, adware, spam, viruses, browser-based attacks, phishing, online fraud and identity theft.

It seems cool, a different approach the the anit-phishing type stuff. Basically you get a simple security report about the sites you visit. The report comes in the flavour of a traffic light in your browser toolbar, green is safe - red is not. Another nice touch is the traffic light is added to our google results, so before you even click on a site you can determine how 'hostile' the webmaster may be.

The software is currently in beta, so it's a temporary free offering, hopefully it's be a free for personal use thing :D
