The first beta of Opera 10.60 was released only two weeks ago, and on Thursday it graduates to a wide release and sheds its beta tag. Opera 10.60 for Windows, Mac, and Linux incorporates security enhancements provided by popular freeware antivirus vendor AVG, improves performance, adds further HTML5 compatibility, and makes a minor but noticeable tweak to the browser interface.

The new security feature indicates that while Chrome and Firefox are looking to further isolate plug-ins and add-ons, Opera hopes to address the immediate threat from malware-infected Web sites. Opera now comes with AVG's real-time Web threat data feed built in. What this means is that when you encounter a page that's been detected by the AVG network to be malicious, you'll see the warning instead. The network is fed by data supplied anonymously by 51 million AVG users from around the world.
