Hey guys so I have a Macbook running OSX 10.9.5 and is running Safari to 7.1.2. I've gotten infected with some type of bug that will constantly open a pop up window to random services like MacKeeper and Purifier. The pop ups are caused when I decide to type information onto a website, I hope that makes sense. Let me give you an example; when you first get to the macrumors website and you click your mouse on the "user" field to type in your username, well as soon as i click on the field a pop up comes up. Then when I go into the password field another pop up comes up. Some of the pop ups are more persistent then others but either way its terrible. Can anyone help?
