AdwareMedic is a program that helps you easily and effectively get rid of any adware components from your system. This application provides you with a simple solution whenever you find yourself dealing with adware issues that modify the way your browser behaves (homepage changes, launched tabs or windows with ads, etc.).
The utility provides you with a clean and intuitive interface and a comprehensive help guide, so any Mac user can easily remove the adware items by using this tool. Another good aspect is that the program automatically updates its adware signatures (info on how to detect adware items) as soon as you launch it.
In my testing, AdwareMedic took less than 10 seconds to scan the entire system and revealed that my Mac lacks adware components.
Nevertheless, if the app manages to find adware components on your Mac and fails to remove them from your system (apparently it might happen according to the info from the homepage of the developer), the developers offer you a solution. You can submit a system snapshot (there's an option on the main menu of the app) and get all the help you need from the support team (from the same developer).
All in all, AdwareMedic proves to be a reliable solution when it comes to removing adware items from your Mac. What's more, this program comes without a price tag. So, I can't find any reason why you shouldn't try it.
