Scam Alert Center keeps you up to date on the latest Phishing threats and calculates risk levels in real-time. You can also download a new toolbar from eBlocs that identifies and blocks phishing attempts, as well as helps users protect themselves from scams, hijacking, spyware, and more. Grab it here.
I haven’t tried it myself so I cannot give it a recommendation at this time. But the alert center is worth a check the next time you receive an email asking for your private information.
