Google has announced that it is taking a step forward in protecting web users from deceptive embedded ads or buttons on websites with Safe Browsing. With the change, Google's Safe Browsing will start looking out for embedded content that tries to do the following:

Pretend to act, or look and feel, like a trusted entity — like your own device or browser, or the website itself.

Try to trick you into doing something you'd only do for a trusted entity — like sharing a password or calling tech support.

Essentially, you should start seeing warnings when websites contain annoying ads that tell you something is out of date on your machine, or buttons that try to imitate the look and feel of legitimate buttons on a website. Since Safe Browsing is on by default in Chrome, users of the browser should start seeing the effects of these changes immediately.
