According to a new study published by the NSS lab on Monday, Internet Explorer 10 can defend against almost all malicious websites on Windows 8.
In addition to IE10, the NSS Lab also tested Google Chrome 25/26, Mozilla Firefox 19, Apple Safari 5, and Opera 12. These browsers are tested on virtual machines running Windows 8 Enterprise Edition.
Test results:
IE10 blocked up to 99.96% malicious websites in tests, Chrome blocked 83.16% in two versions, Safari 5 blocked only 10.15%, Firefox 19 blocked 9.92%, and Opera 12 scored the worst, only block 1.87% of malicious websites.
The NSS lab concluded that both IE10 and Chrome "leverage the file reputation and URL Reputation System and website blocking technology and achieve positive results".
