Coupon Crusher removal instructions
What is Coupon Crusher?
Developed by a company called Engaging Apps, Coupon Crusher is a rogue browser extension claiming to save time and money by enabling coupons, comparison shopping, and displaying discounts/special offers when browsing online shopping websites. Although this functionality may seem legitimate, be aware that Coupon Crusher is categorized as adware or a potentially unwanted application. Coupon Crusher 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' permission. After successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, Coupon Crusher generates intrusive online advertisements and tracks users' Internet browsing activity.
Coupon Crusher generates various intrusive online advertisements including pop-up, banner, text-link, interstitial, sponsored link, and targeted video ads. There is a high probability that clicking these advertisements will cause high-risk adware or malware infections. Furthermore, this potentially unwanted application continually monitors users' Internet browsing activity by recording various information, which may be personally identifiable. For example: IP addresses, geo-locations, search queries entered, URLs visited, pages viewed, unique identifier numbers, and other similar details. This behavior may result in serious privacy issues or even identity theft, and therefore, you are strongly advised to eliminate Coupon Crusher adware from your Internet browsers.
Coupon Crusher is similar to other rogue browser extensions developed by Engaging Apps. For example: DealCoaster, Savings Champion, and Stairway to Savings. Neither Coupon Crusher, nor any of these other plug-ins add any real value for the user - their purpose is to generate income by the display of intrusive online ads. Research shows that most users inadvertently install Coupon Crusher via fake downloads (Java updates, browser updates, etc.) and free software download managers employed by freeware download websites such as download.com, soft32.com, softonic.com, amongst many others. Download managers are used to monetize these websites' free services by offering installation of promoted '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 observing each step of the freeware download process and clicking 'Decline' when installation of additional applications is offered. If you are installing downloaded software, select the 'Custom' or 'Advanced' installation options - this will reveal any bundled applications attempting infiltration and allow removal of them from the installation list. Internet users who have installed Coupon Crusher and observe 'Ads by Coupon Crusher' advertisements when surfing the Internet, should follow this removal guide to uninstall Coupon Crusher adware from their Internet browsers.
