Great mouse . I ' d use two if I had two hands . <| sep |> Most adware involves the browser , but toolbars and similar plugins are inside the browser in that they are integrated into and dependent upon the browser program . Outside adware is any adware that is running independent of the browser . Adware that ' s inside the browser is limited by what the browser will allow it to do such as reading files but it return it gets access to the browser ' s internal data , settings , etc . On the other hand outside adware can do anything the browser can do read files , etc . but it doesn ' t have direct access to the browser ' s internal data . Often both are used a toolbarplugin on the inside to record the user ' s browsing , insert ads into web pages , or change settings such as the home page or proxy server and a separate program running on the outside to read history files directly , act as a network proxy that intercepts all the browser ' s traffic , or just to resist being uninstalled . An example of an outside adware is Windows S e c u r i t y r e m ovalremovewindowssecurity 127 . 0 . 0 . 18080 proxy . It runs a local proxy server that intercepts all internet traffic to and from the browser . It can record the full contents and URLs of the pages being visited , inject ads into web pages , and simulate browser activity like clicking on ads .
