What is a phis hing filter and what does it do?

"Phishing" is what some sites do to get your personal info and bank account details to be able to rip you off later. Good browsers and mail providers have phishing filters installed to protect you from phishing attacks. Phishing attempts will be blocked and/or warnings about an attempt will be issued. Note: the Yahoo spellchecker doesn't recognize phishing as a correct word and always tells you to switch it to "phis hing" which of course doesn't make any sense at all...:-(
