MidADdle is one of the newest pieces of spyware that is virtually undetectable by most anti-spyware programs. It is also known as ads234, ads234.com, AdView, and origin.midaddle.com. What Does It Do? When a computer is infected, the MidADdle program keeps track of the websites you visit, every time you surf the web. Occasionally, when you visit a website that has a "keyword," the program will display a huge advertisement in your face.
