Microsoft s Internet Explorer 8 rated tops among five browsers tested by NSS Labs for effectiveness in protecting against malware and phishing attacks. Apple Safari 4, Google Chrome 2, Mozilla Firefox 3, and Opera 10 beta were evaluated as being behind Microsoft IE 8 when it comes to browser protection against phishing and malware. The test process, which lasted over a two-week period in July, evaluated the browsers based on access to live Internet sites and in theory could be duplicated elsewhere.
