Netcraft Anti-Phishing Toolbar

• Traps suspicious URLs containing characters which have no common purpose other than to deceive.
• Enforces display of browser navigational controls (toolbar & address bar) in all windows, to defend against pop up windows which attempt to hide the navigational controls.
• Clearly displays sites' hosting location, including country, helping you to evaluate fraudulent urls (e.g. the real citibank.com or barclays.co.uk sites are unlikely to be hosted in the former Soviet Union).
