Phishing Alarm blocks scam
This unique feature offers protection against the fastest moving threat on the internet. The ?Phishing Alarm? will alert you if you are being the target of a phishing scam. It works by using both a blacklist of known phishing sites and by analysing the URLs and Web sites."
Found a pretty useful product (this is not an advertisement!) called FraudEliminator that blocks phishing and fraud websites. The feature I like is that it also identifies where each website you're viewing is hosted---so you can see what country it's in. And it's free, as all good things are.
My mother recently fell for a phishing scam purporting to be from SunTrust so I installed this on her machine. It's at www.fraudeliminator.com.
Another good one is EarthLink ScamBlocker but it's not quite as easy to use. There's also SpoofStick (www.spoofstick.com).
