Symantec has joined the phray by announcing their own standalone antiphishing tool, called Norton Confidential.
Norton Confidential will warn users of any web browser or e-mail program when they are about to visit a suspected phishing site, and also adds a background encryption layer for the user's web-based passwords. It uses a combination of known "block lists" and heuristic analysis to warn against or block out phishing sites.
