Googles Chrome browser will be blocking Flash ads by default from September 1st. The change is being made to improve performance for users. Google says that concerned advertisers should switch their Flash ads to HTML5. Flash isnt going to die overnight, but this is surely yet another nail in its coffin. If you must have Adobe Flash installed, make sure you are always running the latest version of the software. But, be warned, disabling or disabling Flash in just your browser may not be enough to protect your computer from infection.”]
