Coupon-Samurai removal instructions
What is Coupon-Samurai?
Developed by Engaging Apps, Coupon-Samurai is a rogue browser add-on claiming to save time and money by enabling coupons, comparison shopping, and displaying special deals/discounts available within online stores. Although this seems a useful and legitimate browser extension, be aware that Coupon-Samurai is categorized as adware or a potentially unwanted application. The developers of this rogue browser plug-in employ a deceptive software marketing method called 'bundling' (stealth installation of additional programs together with the chosen software) to install Coupon-Samurai on Internet browsers without users' permission. Following successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, Coupon-Samurai generates numerous intrusive online advertisements including banner, pop-up, interstitial, sponsored link, and targeted video ads. Clicking these advertisements is likely to cause high-risk adware or malware infections.
Furthermore, Coupon-Samurai continually monitors users' Internet browsing activity by collecting various information, which may be personally identifiable. For example: URLs visited, pages viewed, cookies, geo-locations, IP addresses, unique identifier numbers, and other similar details. There is a high probability that this behavior may lead to serious privacy issues or identity theft, and for this reason, you are strongly advised to eliminate Coupon-Samurai from your Internet browsers. Coupon-Samurai is similar to other rogue browser add-ons that use bundling as an installation method such as iDeals, Coupon Finder, RopeInSavings, and so on. Neither Coupon-Samurai, nor any of these other extensions, add any real value for the user - their purpose is to generate revenue by the display of intrusive online advertisements.
Commonly, users infect their computers with adware when downloading free software via small programs called 'download managers' on freeware download websites such as download.com, soft32.com, and 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, reckless download and installation of freeware often results in adware or malware infections. Installation of Coupon-Samurai, or other potentially unwanted applications, can be avoided by closely inspecting each step of the free software downloading process and never accepting installation of any additional programs offered. If you are installing downloaded software, select the 'Custom' or 'Advanced' installation options - this will reveal any hidden applications listed for installation and allow you to decline them. Internet users who have already installed Coupon-Samurai, and observe intrusive online advertisements while browsing the Internet, should read the following removal guide to eliminate this adware from their Internet browsers.
