Or, more safely, perhaps, from http://www.malwarebytes.com. This could, of course, because the Google recommended advertising is at work here.
I'd recommend removing Google as default search engine, restart and put it back in but without the recommended sites option ticked. In IE, to the right of the search bar, click the arrow and go to Manage Search Providers. A restart after removing them all should trigger the Microsoft page to offer you a choice of providers, select Google and tick it to be default but remove the other tick.[/#000ff]
