Google is bolstering its defenses against what it says is the number one complaint among Chrome users, the hijacking of browser settings by malicious code hidden in free downloads such as screensavers, games and video plugins. The company is enhancing the Chrome feature that enables users to reset their browser settings to their original defaults in order to remove all malicious plugins and apps. Besides providing the reset option, Google will also alert users when browser settings have been changed and provide the option of one-click reset.
