A recent post on Google’s Online Security Blog describes security improvements to the Chrome browser, Google’s search engine, and Google’s advertising platform. The changes should make it easier for users to stay away from web sites known to contain unwanted (and presumed harmful) software.
Chrome now detects when you are about to visit a web site known to contain unwanted software, and displays a large red warning message.
Google’s search engine now decreases ranking for sites known to contain unwanted software. That means these kinds of sites should be less likely to appear in the first few pages of Google search results.
Google now checks all advertisements provided by its AdWords system, and disables any with links to sites with unwanted software. Additional details are available on Google’s Advertising Policies site. Google’s primary source of income is AdWords, so it’s comforting to see that they’re willing to take a financial hit (however small) to protect users.
