Phishing is a big problem lately too.
Netcraft is leading the fight against phishing with their new toolbar. The toolbar shows the age of a site and nationality of the hosting, which can immediately clue you into something phishy going on. It also allows you to report phishing sites, and toolbar users will receive notice that confirmed phishing websites are fraudulent.
IE version available and Firefox version on the way...
