What is Coupon Waterfall?
Developed by Engaging Apps, Coupon Waterfall is a rogue browser add-on claiming to save time and money by displaying discounts/special deals available on shopping websites and enabling coupons and comparison shopping.
This may seem legitimate functionality, however, be aware that Coupon Waterfall is considered to be adware or a potentially unwanted application since it employs a deceptive software marketing method called 'bundling' (stealth installation of additional programs together with the chosen software) to install on Internet browsers without users' consent.
After successful infiltration on Internet Explorer, Mozilla Firefox, and Google Chrome, Coupon Waterfall monitors users' Internet browsing activity and generates intrusive online advertisements.
Coupon Waterfall generates various intrusive online advertisements including interstitial, banner, pop-up, text-link, sponsored link, and targeted video ads. There is a high probability that clicking these advertisements will cause high-risk adware or malware infections.
In addition, this potentially unwanted application tracks users' Internet browsing activity by collecting diverse software and hardware information such as IP addresses, geographic locations, search queries entered, URLs visited, pages viewed, unique identifier numbers, and other similar details, which may be personally identifiable.
This behavior may result in serious privacy issues or identity theft, and for this reason, you are strongly advised to eliminate Coupon Waterfall from your Internet browsers.
Coupon Waterfall is similar to other browser add-ons developed by Engaging Apps (for example, Sliding Coupons, Coupon Lasso, and Deal Dropper). None of these add any real value for the user - their purpose is to generate revenue by the display of intrusive online advertisements.
Commonly, users inadvertently install adware such as Coupon Waterfall via fake downloads (Java updates, browser updates, etc.) and free software 'download clients' employed by freeware software websites including download.com, soft32.com, and softonic.com Be aware that most of these websites use small download programs (download clients) to monetize their free services by offering installation of advertised 'virus-free' browser extensions together with the chosen free software.
Thus, careless download and installation of freeware often results in adware or malware infections. This situation can be prevented by closely inspecting each step of the free software download process and clicking 'Decline' when installation of any additional applications is offered.
If you are installing downloaded software, select the 'Custom' or 'Advanced' installation options - this will reveal all applications listed for installation and allow you to decline them.
