Google Adds Speed and Security Tweaks to Chrome Beta
Prerendering and beefed up file download security in Chrome 17 beta
Google released Chrome 17 beta version which comes with improved speed and security. Thanks to the recent changes the browser will start to load some web pages in the background while the user is typing the URL and will examine executable files that are being downloaded in order to warn the user if any of them is malicious.
On the speed front, Google has tweaked the browser so that it will start to load some web pages in the background before the user has finished typing the URL in the address bar/search box. If the URL auto-completes to a site the user is likely to visit, the browser will start to prerender the page before they even hit Enter.
On the security front, Google has made additions to the Safe Browsing technology baked into the browser. Previously Chrome worked to protect users from malicious websites but this has now been expanded to allow it to examine executable files (such as .exe and .msi files) that are being downloaded. If a file is known to be bad, or is hosted on a site that has a relatively high percentage of malicious downloads, Chrome will warn the user that the file appears to be malicious and that it should be discarded.
