CouponDownloader is an adware that will display bothersome advertisements over and over again on web pages that you visit on your preferred browser. They usually show up as blue, double-underlined links that bring up a window showing CouponDownloader ads, as you can see below.
Besides slowing down your computer and the display of the web pages you often visit, CouponDownloader adware is also a problem for your privacy. CouponDownloader is installed as an add-on for Chrome, Firefox and Internet Explorer, and has access to everything you do on your browser. Therefore, it’s going to register your browsing history in order to offer you ads that become more and more personalized. It can also serve as a database that can be sold or shared with third parties. Even if, in theory, the collected data is anonymous, we recommend that you remove CouponDownloader ads from your computer as soon as possible.
