The company bills Internet Explorer 8 as more secure and easier to use than its predecessor, IE7. In Microsoft’s words, the new browser “blocks two to four times more malware attacks than other browsers; cuts down on the time it takes to complete common tasks on the Web such as searching, mapping and sharing, including navigating 15 of the 20 top worldwide sites; and blurs the lines between the services they use daily and the browser used to access the Internet.”

An “Instant Search Box” will enable search from sites including The New York Times, Amazon.com and Wikipedia.

The browser will come automatically packaged with unlaunched Windows 7.
