Google Chrome extensions are programs that can be installed into Chrome in order to change the browser’s functionality. This includes adding new features to Chrome or modifying the existing behavior of the program itself to make it more convenient for the user. As you can see, extensions offer a wide range of extra functionality so that you can perform tasks easier or get more out of the web sites you visit. Unfortunately, while most Chrome extensions are beneficial, there are some developers that create extensions that modify the behavior of Chrome in a negative way. For example, adware developers may install Chrome extensions without your permission that inject advertisements on to web pages that you are viewing, change your search provider to a site under their control, change the new tab page, or hijack your home page.
